-commit 8d02e4c6c5e1e8676251b0717a46054267091cb4

-    Disable logging in parallel workers
-    
-    When a query uses parallel workers, pgaudit will log the same query for
-    every parallel worker. This is undesireable since it can result in log
-    amplification for queries that use parallel workers.

-# PostGIS Testing in Neon
-
-This directory contains configuration files and patches for running PostGIS tests in the Neon database environment.
-
-## Overview
-
-PostGIS is a spatial database extension for PostgreSQL that adds support for geographic objects. Testing PostGIS compatibility ensures that Neon's modifications to PostgreSQL don't break compatibility with this critical extension.
-
-## PostGIS Versions
-
- PostgreSQL v17: PostGIS 3.5.0
- PostgreSQL v14/v15/v16: PostGIS 3.3.3
-
-## Test Configuration
-
-The test setup includes:
-
- `postgis-no-upgrade-test.patch`: Disables upgrade tests by removing the upgrade test section from regress/runtest.mk
- `postgis-regular-v16.patch`: Version-specific patch for PostgreSQL v16
- `postgis-regular-v17.patch`: Version-specific patch for PostgreSQL v17
- `regular-test.sh`: Script to run PostGIS tests as a regular user
- `neon-test.sh`: Script to handle version-specific test configurations
- `raster_outdb_template.sql`: Template for raster tests with explicit file paths
-
-## Excluded Tests
-
-**Important Note:** The test exclusions listed below are specifically for regular-user tests against staging instances. These exclusions are necessary because staging instances run with limited privileges and cannot perform operations requiring superuser access. Docker-compose based tests are not affected by these exclusions.
-
-### Tests Requiring Superuser Permissions
-
-These tests cannot be run as a regular user:
- `estimatedextent`
- `regress/core/legacy`
- `regress/core/typmod`
- `regress/loader/TestSkipANALYZE`
- `regress/loader/TestANALYZE`
-
-### Tests Requiring Filesystem Access
-
-These tests need direct filesystem access that is only possible for superusers:
- `loader/load_outdb`
-
-### Tests with Flaky Results
-
-These tests have assumptions that don't always hold true:
- `regress/core/computed_columns` - Assumes computed columns always outperform alternatives, which is not consistently true
-
-### Tests Requiring Tunable Parameter Modifications
-
-These tests attempt to modify the `postgis.gdal_enabled_drivers` parameter, which is only accessible to superusers:
- `raster/test/regress/rt_wkb`
- `raster/test/regress/rt_addband`
- `raster/test/regress/rt_setbandpath`
- `raster/test/regress/rt_fromgdalraster`
- `raster/test/regress/rt_asgdalraster`
- `raster/test/regress/rt_astiff`
- `raster/test/regress/rt_asjpeg`
- `raster/test/regress/rt_aspng`
- `raster/test/regress/permitted_gdal_drivers`
- Loader tests: `BasicOutDB`, `Tiled10x10`, `Tiled10x10Copy`, `Tiled8x8`, `TiledAuto`, `TiledAutoSkipNoData`, `TiledAutoCopyn`
-
-### Topology Tests (v17 only)
- `populate_topology_layer`
- `renametopogeometrycolumn`
-
-## Other Modifications
-
- Binary.sql tests are modified to use explicit file paths
- Server-side SQL COPY commands (which require superuser privileges) are converted to client-side `\copy` commands
- Upgrade tests are disabled

-# Memo: Endpoint Persistent Unlogged Files Storage
-Created on 2024-11-05
-Implemented on N/A
-
-## Summary
-A design for a storage system that allows storage of files required to make
-Neon's Endpoints have a better experience at or after a reboot.
-
-## Motivation
-Several systems inside PostgreSQL (and Neon) need some persistent storage for
-optimal workings across reboots and restarts, but still work without.
-Examples are the query-level statistics files of `pg_stat_statements` in
-`pg_stat/pg_stat_statements.stat`, and `pg_prewarm`'s `autoprewarm.blocks`.
-We need a storage system that can store and manage these files for each
-Endpoint, without necessarily granting users access to an unlimited storage
-device.
-
-## Goals
- Store known files for Endpoints with reasonable persistence.  
-  _Data loss in this service, while annoying and bad for UX, won't lose any
-  customer's data._
-
-## Non Goals (if relevant)
- This storage system does not need branching, file versioning, or other such
-  features. The files are as ephemeral to the timeline of the data as the
-  Endpoints that host the data.
- This storage system does not need to store _all_ user files, only 'known'
-  user files.
- This storage system does not need to be hosted fully inside Computes.  
-  _Instead, this will be a separate component similar to Pageserver,
-  SafeKeeper, the S3 proxy used for dynamically loaded extensions, etc._
-
-## Impacted components
- Compute needs new code to load and store these files in its lifetime.
- Control Plane needs to consider this new storage system when signalling
-  the deletion of an Endpoint, Timeline, or Tenant.
- Control Plane needs to consider this new storage system when it resets
-  or re-assigns an endpoint's timeline/branch state.
-
-A new service is created: the Endpoint Persistent Unlogged Files Storage
-service.  This could be integrated in e.g. Pageserver or Control Plane, or a
-separately hosted service.
-
-## Proposed implementation
-Endpoint-related data files are managed by a newly designed service (which
-optionally is integrated in an existing service like Pageserver or Control
-Plane), which stores data directly into S3 or any blob storage of choice.
-
-Upon deletion of the Endpoint, or reassignment of the endpoint to a different
-branch, this ephemeral data is dropped: the data stored may not match the
-state of the branch's data after reassignment, and on endpoint deletion the
-data won't have any use to the user.
-
-Compute gets credentials (JWT token with Tenant, Timeline & Endpoint claims)
-which it can use to authenticate to this new service and retrieve and store
-data associated with this endpoint.  This limited scope reduces leaks of data
-across endpoints and timeline resets, and limits the ability of endpoints to
-mess with other endpoints' data.
-
-The path of this endpoint data in S3 is initially as follows:
-
-    s3://<regional-epufs-bucket>/
-      tenants/
-        <hex-tenant-id>/
-          tenants/
-            <hex-timeline-id>/
-              endpoints/
-                <endpoint-id>/
-                  pgdata/
-                    <file_path_in_pgdatadir>
-
-For other blob storages an equivalent or similar path can be constructed.
-
-### Reliability, failure modes and corner cases (if relevant)
-Reliability is important, but not critical to the workings of Neon.  The data
-stored in this service will, when lost, reduce performance, but won't be a
-cause of permanent data loss - only operational metadata is stored.
-
-Most, if not all, blob storage services have sufficiently high persistence
-guarantees to cater our need for persistence and uptime. The only concern with
-blob storages is that the access latency is generally higher than local disk,
-but for the object types stored (cache state, ...) I don't think this will be
-much of an issue.
-
-### Interaction/Sequence diagram (if relevant)
-
-In these diagrams you can replace S3 with any persistent storage device of
-choice, but S3 is chosen as representative name: The well-known and short name
-of AWS' blob storage. Azure Blob Storage should work too, but it has a much
-longer name making it less practical for the diagrams.

-
-### Scalability (if relevant)
-
-Provisionally:  As this service is going to be part of compute startup, this
-service should be able to quickly respond to all requests.  Therefore this
-service is deployed to every AZ we host Computes in, and Computes communicate
-(generally) only to the EPUFS endpoint of the AZ they're hosted in.
-
-Local caching of frequently restarted endpoints' data or metadata may be
-needed for best performance.  However, due to the regional nature of stored
-data but zonal nature of the service deployment, we should be careful when we
-implement any local caching, as it is possible that computes in AZ 1 will
-update data originally written and thus cached by AZ 2.  Cache version tests
-and invalidation is therefore required if we want to roll out caching to this
-service, which is too broad a scope for an MVC.  This is why caching is left
-out of scope for this RFC, and should be considered separately after this RFC
-is implemented.
-
-### Security implications (if relevant)
-This service must be able to authenticate users at least by Tenant ID,
-Timeline ID and Endpoint ID. This will use the existing JWT infrastructure of
-Compute, which will be upgraded to the extent needed to support Timeline- and
-Endpoint-based claims.
-
-The service requires unlimited access to (a prefix of) a blob storage bucket,
-and thus must be hosted outside the Compute VM sandbox.
-
-A service that generates pre-signed request URLs for Compute to download the
-data from that URL is likely problematic, too:  Compute would be able to write
-unlimited data to the bucket, or exfiltrate this signed URL to get read/write
-access to specific objects in this bucket, which would still effectively give
-users access to the S3 bucket (but with improved access logging).
-
-There may be a use case for transferring data associated with one endpoint to
-another endpoint (e.g. to make one endpoint warm its caches with the state of
-another endpoint), but that's not currently in scope, and specific needs may
-be solved through out-of-line communication of data or pre-signed URLs.
-
-### Unresolved questions (if relevant)
-Caching of files is not in the implementation scope of the document, but
-should at some future point be considered to maximize performance.
-
-## Alternative implementation (if relevant)
-Several ideas have come up to solve this issue:
-
-### Use AUXfile
-One prevalent idea was to WAL-log the files using our AUXfile mechanism.
-
-Benefits:
-
-+ We already have this storage mechanism
-
-Demerits:
-
- It isn't available on read replicas
- Additional WAL will be consumed during shutdown and after the shutdown
-  checkpoint, which needs PG modifications to work without panics.
- It increases the data we need to manage in our versioned storage, thus
-  causing higher storage costs with higher retention due to duplication at
-  the storage layer.
-
-### Sign URLs for read/write operations, instead of proxying them
-
-Benefits:
-
-+ The service can be implemented with a much reduced IO budget
-
-Demerits:
-
- Users could get access to these signed credentials
- Not all blob storage services may implement URL signing
-
-### Give endpoints each their own directly accessed block volume
-
-Benefits:
-
-+ Easier to integrate for PostgreSQL
-
-Demerits:
-
- Little control on data size and contents
- Potentially problematic as we'd need to store data all across the pgdata
-  directory.
- EBS is not a good candidate
-   - Attaches in 10s of seconds, if not more; i.e. too cold to start
-   - Shared EBS volumes are a no-go, as you'd have to schedule the endpoint
-     with users of the same EBS volumes, which can't work with VM migration
-   - EBS storage costs are very high (>80$/kilotenant when using a
-     volume/tenant)
-   - EBS volumes can't be mounted across AZ boundaries
- Bucket per endpoint is unfeasible
-   - S3 buckets are priced at $20/month per 1k, which we could better spend
-     on developers.
-   - Allocating service accounts takes time (100s of ms), and service accounts
-     are a limited resource, too; so they're not a good candidate to allocate
-     on a per-endpoint basis.
-   - Giving credentials limited to prefix has similar issues as the pre-signed
-     URL approach.
-   - Bucket DNS lookup will fill DNS caches and put pressure on DNS lookup
-     much more than our current systems would.
- Volumes bound by hypervisor are unlikely
-   - This requires significant investment and increased software on the
-     hypervisor.
-   - It is unclear if we can attach volumes after boot, i.e. for pooled
-     instances.
-
-### Put the files into a table
-
-Benefits:
-
- + Mostly already available in PostgreSQL
-
-Demerits:
-
- - Uses WAL
-   - Can't be used after shutdown checkpoint
-   - Needs a RW endpoint, and table & catalog access to write to this data
- - Gets hit with DB size limitations
- - Depending on user acces:
-   - Inaccessible:  
-     The user doesn't have control over database size caused by
-     these systems.
-   - Accessible:  
-     The user can corrupt these files and cause the system to crash while
-     user-corrupted files are present, thus increasing on-call overhead.
-
-## Definition of Done (if relevant)
-
-This project is done if we have:
-
- One S3 bucket equivalent per region, which stores this per-endpoint data.
- A new service endpoint in at least every AZ, which indirectly grants
-  endpoints access to the data stored for these endpoints in these buckets.
- Compute writes & reads temp-data at shutdown and startup, respectively, for
-  at least the pg_prewarm or lfc_prewarm state files.
- Cleanup of endpoint data is triggered when the endpoint is deleted or is
-  detached from its current timeline.

-# Storage Feature Flags
-
-In this RFC, we will describe how we will implement per-tenant feature flags.
-
-## PostHog as Feature Flag Service
-
-Before we start, let's talk about how current feature flag services work. PostHog is the feature flag service we are currently using across multiple user-facing components in the company. PostHog has two modes of operation: HTTP evaluation and server-side local evaluation.
-
-Let's assume we have a storage feature flag called gc-compaction and we want to roll it out to scale-tier users with resident size >= 10GB and <= 100GB.
-
-### Define User Profiles
-
-The first step is to synchronize our user profiles to the PostHog service. We can simply assume that each tenant is a user in PostHog. Each user profile has some properties associated with it. In our case, it will be: plan type (free, scale, enterprise, etc); resident size (in bytes); primary pageserver (string); region (string).
-
-### Define Feature Flags
-
-We would create a feature flag called gc-compaction in PostHog with 4 variants: disabled, stage-1, stage-2, fully-enabled. We will flip the feature flags from disabled to fully-enabled stage by stage for some percentage of our users.
-
-### Option 1: HTTP Evaluation Mode
-
-When using PostHog's HTTP evaluation mode, the client will make request to the PostHog service, asking for the value of a feature flag for a specific user.
-
-* Control plane will report the plan type to PostHog each time it attaches a tenant to the storcon or when the user upgrades/downgrades. It calls the PostHog profile API to associate tenant ID with the plan type. Assume we have X active tenants and such attach or plan change event happens each week, that would be 4X profile update requests per month.
-* Pageservers will report the resident size and the primary pageserver to the PostHog service. Assume we report resident size every 24 hours, that would be 30X requests per month.
-* Each tenant will request the state of the feature flag every 1 hour, that's 720X requests per month.
-* The Rust client would be easy to implement as we only need to call the `/decide` API on PostHog.
-
-Using the HTTP evaluation mode we will issue 754X requests a month.
-
-### Option 2: Local Evaluation Mode
-
-When using PostHog's HTTP evaluation mode, the client (usually the server in a browser/server architecture) will poll the feature flag configuration every 30s (default in the Python client) from PostHog. Such configuration contains data like:
-
-<details>
-
-<summary>Example JSON response from the PostHog local evaluation API</summary>
-
-```
-[
-    {
-        "id": 1,
-        "name": "Beta Feature",
-        "key": "person-flag",
-        "is_simple_flag": True,
-        "active": True,
-        "filters": {
-            "groups": [
-                {
-                    "properties": [
-                        {
-                            "key": "location",
-                            "operator": "exact",
-                            "value": ["Straße"],
-                            "type": "person",
-                        }
-                    ],
-                    "rollout_percentage": 100,
-                },
-                {
-                    "properties": [
-                        {
-                            "key": "star",
-                            "operator": "exact",
-                            "value": ["ſun"],
-                            "type": "person",
-                        }
-                    ],
-                    "rollout_percentage": 100,
-                },
-            ],
-        },
-    }
-]
-```
-
-</details>
-
-Note that the API only contains information like "under what condition => rollout percentage". The user is responsible to provide the properties required to the client for local evaluation, and the PostHog service (web UI) cannot know if a feature is enabled for the tenant or not until the client uses the `capture` API to report the result back. To control the rollout percentage, the user ID gets mapped to a float number in `[0, 1)` on a consistent hash ring. All values <= the percentage will get the feature enabled or set to the desired value.
-
-To use the local evaluation mode, the system needs:
-
-* Assume each pageserver will poll PostHog for the local evaluation JSON every 5 minutes (instead of the 30s default as it's too frequent). That's 8640Y per month, Y is the number of pageservers. Local evaluation requests cost 10x more than the normal decide request, so that's 86400Y request units to bill.
-* Storcon needs to store the plan type in the database and pass that information to the pageserver when attaching the tenant.
-* Storcon also needs to update PostHog with the active tenants, for example, when the tenant gets detached/attached. Assume each active tenant gets detached/attached every week, that would be 4X requests per month.
-* We do not need to update bill type or resident size to PostHog as all these are evaluated locally.
-* After each local evaluation of the feature flag, we need to call PostHog's capture event API to update the result of the evaluation that the feature is enabled. We can do this when the flag gets changed compared with the last cached state in memory. That would be at least 4X (assume we do deployment every week so the cache gets cleared) and maybe an additional multiplifier of 10 assume we have 10 active features.
-
-In this case, we will issue 86400Y + 40X requests per month.
-
-Assume X = 1,000,000 and Y = 100,
-
-|   | HTTP Evaluation  | Local Evaluation  |
-|---|---|---|
-| Latency of propagating the conditions/properties for feature flag  | 24 hours  | available locally  |
-| Latency of applying the feature flag  | 1 hour  | 5 minutes  |
-| Can properties be reported from different services |  Yes |  No  |
-| Do we need to sync billing info etc to pageserver |  No |  Yes  |
-| Cost | 75400$ / month | 4864$ / month |
-
-# Our Solution
-
-We will use PostHog _only_ as an UI to configure the feature flags. Whether a feature is enabled or not can only be queried through storcon/pageserver instead of using the PostHog UI. (We could report it back to PostHog via `capture_event` but it costs $$$.) This allows us to ramp up the feature flag functionality fast at first. At the same time, it would also give us the option to migrate to our own solution once we want to have more properties and more complex evaluation rules in our system.
-
-* We will create several fake users (tenants) in PostHog that contains all the properties we will use for evaluating a feature flag (i.e., resident size, billing type, pageserver id, etc.)
-* We will use PostHog's local evaluation API to poll the configuration of the feature flags and evaluate them locally on each of the pageserver.
-* The evaluation result will not be reported back to PostHog.
-* Storcon needs to pull some information from cplane database.
-* To know if a feature is currently enabled or not, we need to call the storcon/pageserver API; and we won't be able to know if a feature has been enabled on a tenant before easily: we need to look at the Grafana logs.
-
-We only need to pay for the 86400Y local evaluation requests (that would be setting Y=0 in solution 2 => $864/month, and even less if we proxy it through storcon).
-
-## Implementation
-
-* Pageserver: implement a PostHog local evaluation client. The client will be shared across all tenants on the pageserver with a single API: `evaluate(tenant_id, feature_flag, properties) -> json`.
-* Storcon: if we need plan type as the evaluation condition, pull it from cplane database.
-* Storcon/Pageserver: implement an HTTP API `:tenant_id/feature/:feature` to retrieve the current feature flag status.
-* Storcon/Pageserver: a loop to update the feature flag spec on both storcon and pageserver. Pageserver loop will only be activated if storcon does not push the specs to the pageserver.
-
-## Difference from Tenant Config
-
-* Feature flags can be modified by percentage, and the default config for each feature flag can be modified in UI without going through the release process.
-* Feature flags are more flexible and won't be persisted anywhere and will be passed as plain JSON over the wire so that do not need to handle backward/forward compatibility as in tenant config.
-* The expectation of tenant config is that once we add a flag we cannot remove it (or it will be hard to remove), but feature flags are more flexible.
-
-# Final Implementation
-
-* We added a new crate `posthog_lite_client` that supports local feature evaluations.
-* We set up two projects "Storage (staging)" and "Storage (production)" in the PostHog console.
-* Each pageserver reports 10 fake tenants to PostHog so that we can get all combinations of regions (and other properties) in the PostHog UI.
-* Supported properties: AZ, neon_region, pageserver, tenant_id.
-* You may use "Pageserver Feature Flags" dashboard to see the evaluation status.
-* The feature flag spec is polled on storcon every 30s (in each of the region) and storcon will propagate the spec to the pageservers.
-* The pageserver housekeeping loop updates the tenant-specific properties (e.g., remote size) for evaluation.
-
-Each tenant has a `feature_resolver` object. After you add a feature flag in the PostHog console, you can retrieve it with:
-
-```rust
-// Boolean flag
-self
-    .feature_resolver
-    .evaluate_boolean("flag")
-    .is_ok()
-// Multivariate flag
-self
-    .feature_resolver
-    .evaluate_multivariate("gc-comapction-strategy")
-    .ok();
-```
-
-The user needs to handle the case where the evaluation result is an error. This can occur in a variety of cases:
-
-* During the pageserver start, the feature flag spec has not been retrieved.
-* No condition group is matched.
-* The feature flag spec contains an operand/operation not supported by the lite PostHog library.
-
-For boolean flags, the return value is `Result<(), Error>`. `Ok(())` means the flag is evaluated to true. Otherwise,
-there is either an error in evaluation or it does not match any groups.
-
-For multivariate flags, the return value is `Result<String, Error>`. `Ok(variant)` indicates the flag is evaluated
-to a variant. Otherwise, there is either an error in evaluation or it does not match any groups.
-
-The evaluation logic is documented in the PostHog lite library. It compares the consistent hash of a flag key + tenant_id
-with the rollout percentage and determines which tenant to roll out a specific feature.
-
-Users can use the feature flag evaluation API to get the flag evaluation result of a specific tenant for debugging purposes.
-
-```
-curl http://localhost:9898/v1/tenant/:tenant_id/feature_flag?flag=:key&as=multivariate/boolean"
-```
-
-By default, the storcon pushes the feature flag specs to the pageservers every 30 seconds, which means that a change in feature flag in the
-PostHog UI will propagate to the pageservers within 30 seconds.
-
-# Future Works
-
-* Support dynamic tenant properties like logical size as the evaluation condition.
-* Support properties like `plan_type` (needs cplane to pass it down).
-* Report feature flag evaluation result back to PostHog (if the cost is okay).
-* Fast feature flag evaluation cache on critical paths (e.g., cache a feature flag result in `AtomicBool` and use it on the read path).

-# Compute rolling restart with prewarm
-
-Created on 2025-03-17
-Implemented on _TBD_
-Author: Alexey Kondratov (@ololobus)
-
-## Summary
-
-This RFC describes an approach to reduce performance degradation due to missing caches after compute node restart, i.e.:
-
-1. Rolling restart of the running instance via 'warm' replica.
-2. Auto-prewarm compute caches after unplanned restart or scale-to-zero.
-
-## Motivation
-
-Neon currently implements several features that guarantee high uptime of compute nodes:
-
-1. Storage high-availability (HA), i.e. each tenant shard has a secondary pageserver location, so we can quickly switch over compute to it in case of primary pageserver failure.
-2. Fast compute provisioning, i.e. we have a fleet of pre-created empty computes, that are ready to serve workload, so restarting unresponsive compute is very fast.
-3. Preemptive NeonVM compute provisioning in case of k8s node unavailability.
-
-This helps us to be well-within the uptime SLO of 99.95% most of the time. Problems begin when we go up to multi-TB workloads and 32-64 CU computes.
-During restart, compute loses all caches: LFC, shared buffers, file system cache. Depending on the workload, it can take a lot of time to warm up the caches,
-so that performance could be degraded and might be even unacceptable for certain workloads. The latter means that although current approach works well for small to
-medium workloads, we still have to do some additional work to avoid performance degradation after restart of large instances.
-
-## Non Goals
-
- Details of the persistence storage for prewarm data are out of scope, there is a separate RFC for that: <https://github.com/neondatabase/neon/pull/9661>.
- Complete compute/Postgres HA setup and flow. Although it was originally in scope of this RFC, during preliminary research it appeared to be a rabbit hole, so it's worth of a separate RFC.
- Low-level implementation details for Postgres replica-to-primary promotion. There are a lot of things to think and care about: how to start walproposer, [logical replication failover](https://www.postgresql.org/docs/current/logical-replication-failover.html), and so on, but it's worth of at least a separate one-pager design document if not RFC.
-
-## Impacted components
-
-Postgres, compute_ctl, Control plane, Endpoint storage for unlogged storage of compute files.
-For the latter, we will need to implement a uniform abstraction layer on top of S3, ABS, etc., but
-S3 is used in text interchangeably with 'endpoint storage' for simplicity.
-
-## Proposed implementation
-
-### compute_ctl spec changes and auto-prewarm
-
-We are going to extend the current compute spec with the following attributes
-
-```rust
-struct ComputeSpec {
-    /// [All existing attributes]
-    ...
-    /// Whether to do auto-prewarm at start or not.
-    /// Default to `false`.
-    pub lfc_auto_prewarm: bool
-    /// Interval in seconds between automatic dumps of
-    /// LFC state into S3. Default `None`, which means 'off'.
-    pub lfc_dump_interval_sec: Option<i32>
-}
-```
-
-When `lfc_dump_interval_sec` is set to `N`, `compute_ctl` will periodically dump the LFC state
-and store it in S3, so that it could be used either for auto-prewarm after restart or by replica
-during the rolling restart. For enabling periodic dumping, we should consider the following value
-`lfc_dump_interval_sec=300` (5 minutes), same as in the upstream's `pg_prewarm.autoprewarm_interval`.
-
-When `lfc_auto_prewarm` is set to `true`, `compute_ctl` will start prewarming the LFC upon restart
-iif some of the previous states is present in S3.
-
-### compute_ctl API
-
-1. `POST /store_lfc_state` -- dump LFC state using Postgres SQL interface and store result in S3.
-    This has to be a blocking call, i.e. it will return only after the state is stored in S3.
-    If there is any concurrent request in progress, we should return `429 Too Many Requests`,
-    and let the caller to retry.
-
-2. `GET /dump_lfc_state` -- dump LFC state using Postgres SQL interface and return it as is
-    in text format suitable for the future restore/prewarm. This API is not strictly needed at
-    the end state, but could be useful for a faster prototyping of a complete rolling restart flow
-    with prewarm, as it doesn't require persistent for LFC state storage.
-
-3. `POST /restore_lfc_state` -- restore/prewarm LFC state with request
-
-    ```yaml
-    RestoreLFCStateRequest:
-      oneOf:
-        - type: object
-          required:
-            - lfc_state
-          properties:
-            lfc_state:
-              type: string
-              description: Raw LFC content dumped with GET `/dump_lfc_state`
-        - type: object
-          required:
-            - lfc_cache_key
-          properties:
-            lfc_cache_key:
-              type: string
-              description: |
-                endpoint_id of the source endpoint on the same branch
-                to use as a 'donor' for LFC content. Compute will look up
-                LFC content dump in S3 using this key and do prewarm.
-    ```
-
-    where `lfc_state` and `lfc_cache_key` are mutually exclusive.
-
-    The actual prewarming will happen asynchronously, so the caller need to check the
-    prewarm status using the compute's standard `GET /status` API.
-
-4. `GET /status` -- extend existing API with following attributes
-
-    ```rust
-    struct ComputeStatusResponse {
-        // [All existing attributes]
-        ...
-        pub prewarm_state: PrewarmState
-    }
-
-    /// Compute prewarm state. Will be stored in the shared Compute state
-    /// in compute_ctl
-    struct PrewarmState {
-        pub status: PrewarmStatus
-        /// Total number of pages to prewarm
-        pub pages_total: i64
-        /// Number of pages prewarmed so far
-        pub pages_processed: i64
-        /// Optional prewarm error
-        pub error: Option<String>
-    }
-
-    pub enum PrewarmStatus {
-        /// Prewarming was never requested on this compute
-        Off,
-        /// Prewarming was requested, but not started yet
-        Pending,
-        /// Prewarming is in progress. The caller should follow
-        /// `PrewarmState::progress`.
-        InProgress,
-        /// Prewarming has been successfully completed
-        Completed,
-        /// Prewarming failed. The caller should look at
-        /// `PrewarmState::error` for the reason.
-        Failed,
-        /// It is intended to be used by auto-prewarm if none of
-        /// the previous LFC states is available in S3.
-        /// This is a distinct state from the `Failed` because
-        /// technically it's not a failure and could happen if
-        /// compute was restart before it dumped anything into S3,
-        /// or just after the initial rollout of the feature.
-        Skipped,
-    }
-    ```
-
-5. `POST /promote` -- this is a **blocking** API call to promote compute replica into primary.
-    This API should be very similar to the existing `POST /configure` API, i.e. accept the
-    spec (primary spec, because originally compute was started as replica). It's a distinct
-    API method because semantics and response codes are different:
-
-    - If promotion is done successfully, it will return `200 OK`.
-    - If compute is already primary, the call will be no-op and `compute_ctl`
-      will return `412 Precondition Failed`.
-    - If, for some reason, second request reaches compute that is in progress of promotion,
-      it will respond with `429 Too Many Requests`.
-    - If compute hit any permanent failure during promotion `500 Internal Server Error`
-      will be returned.
-
-### Control plane operations
-
-The complete flow will be present as a sequence diagram in the next section, but here
-we just want to list some important steps that have to be done by control plane during
-the rolling restart via warm replica, but without much of low-level implementation details.
-
-1. Register the 'intent' of the instance restart, but not yet interrupt any workload at
-    primary and also accept new connections. This may require some endpoint state machine
-    changes, e.g. introduction of the `pending_restart` state. Being in this state also
-    **mustn't prevent any other operations except restart**: suspend, live-reconfiguration
-    (e.g. due to notify-attach call from the storage controller), deletion.
-
-2. Start new replica compute on the same timeline and start prewarming it. This process
-    may take quite a while, so the same concurrency considerations as in 1. should be applied
-    here as well.
-
-3. When warm replica is ready, control plane should:
-
-    3.1. Terminate the primary compute. Starting from here, **this is a critical section**,
-        if anything goes off, the only option is to start the primary normally and proceed
-        with auto-prewarm.
-
-    3.2. Send cache invalidation message to all proxies, notifying them that all new connections
-        should request and wait for the new connection details. At this stage, proxy has to also
-        drop any existing connections to the old primary, so they didn't do stale reads.
-
-    3.3. Attach warm replica compute to the primary endpoint inside control plane metadata
-        database.
-
-    3.4. Promote replica to primary.
-
-    3.5. When everything is done, finalize the endpoint state to be just `active`.

-### Network bandwidth and prewarm speed
-
-It's currently known that pageserver can sustain about 3000 RPS per shard for a few running computes.
-Large tenants are usually split into 8 shards, so the final formula may look like this:
-
-```text
-8 shards * 3000 RPS * 8 KB =~ 190 MB/s
-```
-
-so depending on the LFC size, prewarming will take at least:
-
- ~5s for 1 GB
- ~50s for 10 GB
- ~5m for 100 GB
- \>1h for 1 TB
-
-In total, one pageserver is normally capped by 30k RPS, so it obviously can't sustain many computes
-doing prewarm at the same time. Later, we may need an additional mechanism for computes to throttle
-the prewarming requests gracefully.
-
-### Reliability, failure modes and corner cases
-
-We consider following failures while implementing this RFC:
-
-1. Compute got interrupted/crashed/restarted during prewarm. The caller -- control plane -- should
-    detect that and start prewarm from the beginning.
-
-2. Control plane promotion request timed out or hit network issues. If it never reached the
-    compute, control plane should just repeat it. If it did reach the compute, then during
-    retry control plane can hit `409` as previous request triggered the promotion already.
-    In this case, control plane need to retry until either `200` or
-    permanent error `500` is returned.
-
-3. Compute got interrupted/crashed/restarted during promotion. At restart it will ask for
-    a spec from control plane, and its content should signal compute to start as **primary**,
-    so it's expected that control plane will continue polling for certain period of time and
-    will discover that compute is ready to accept connections if restart is fast enough.
-
-4. Any other unexpected failure or timeout during prewarming. This **failure mustn't be fatal**,
-    control plane has to report failure, terminate replica and keep primary running.
-
-5. Any other unexpected failure or timeout during promotion. Unfortunately, at this moment
-    we already have the primary node stopped, so the only option is to start primary again
-    and proceed with auto-prewarm.
-
-6. Any unexpected failure during auto-prewarm. This **failure mustn't be fatal**,
-    `compute_ctl` has to report the failure, but do not crash the compute.
-
-7. Control plane failed to confirm that old primary has terminated. This can happen, especially
-    in the future HA setup. In this case, control plane has to ensure that it sent VM deletion
-    and pod termination requests to k8s, so long-term we do not have two running primaries
-    on the same timeline.
-
-### Security implications
-
-There are two security implications to consider:
-
-1. Access to `compute_ctl` API. It has to be accessible from the outside of compute, so all
-    new API methods have to be exposed on the **external** HTTP port and **must** be authenticated
-    with JWT.
-
-2. Read/write only your own LFC state data in S3. Although it's not really a security concern,
-    since LFC state is just a mapping of blocks present in LFC at certain moment in time;
-    it still has to be highly restricted, so that i) only computes on the same timeline can
-    read S3 state; ii) each compute can only write to the path that contains it's `endpoint_id`.
-    Both of this must be validated by Endpoint storage service using the JWT token provided by `compute_ctl`.
-
-### Unresolved questions
-
-#### Billing, metrics and monitoring
-
-Currently, we only label computes with `endpoint_id` after attaching them to the endpoint.
-In this proposal, this means that temporary replica will remain unlabelled until it's promoted
-to primary. We can also hide it from users in the control plane API, but what to do with
-billing and monitoring is still unclear.
-
-We can probably mark it as 'billable' and tag with `project_id`, so it will be billed, but
-not interfere in any way with the current primary monitoring.
-
-Another thing to consider is how logs and metrics export will switch to the new compute.
-It's expected that OpenTelemetry collector will auto-discover the new compute and start
-scraping metrics from it.
-
-#### Auto-prewarm
-
-It's still an open question whether we need auto-prewarm at all. The author's gut-feeling is
-that yes, we need it, but might be not for all workloads, so it could end up exposed as a
-user-controllable knob on the endpoint. There are two arguments for that:
-
-1. Auto-prewarm existing in upstream's `pg_prewarm`, _probably for a reason_.
-
-2. There are still could be 2 flows when we cannot perform the rolling restart via the warm
-    replica: i) any failure or interruption during promotion; ii) wake up after scale-to-zero.
-    The latter might be challenged as well, i.e. one can argue that auto-prewarm may and will
-    compete with user-workload for storage resources. This is correct, but it might as well
-    reduce the time to get warm LFC and good performance.
-
-#### Low-level details of the replica promotion
-
-There are many things to consider here, but three items just off the top of my head:
-
-1. How to properly start the `walproposer` inside Postgres.
-
-2. What to do with logical replication. Currently, we do not include logical replication slots
-    inside basebackup, because nobody advances them at replica, so they just prevent the WAL
-    deletion. Yet, we do need to have them at primary after promotion. Starting with Postgres 17,
-    there is a new feature called
-    [logical replication failover](https://www.postgresql.org/docs/current/logical-replication-failover.html)
-    and `synchronized_standby_slots` setting, but we need a plan for the older versions. Should we
-    request a new basebackup during promotion?
-
-3. How do we guarantee that replica will receive all the latest WAL from safekeepers? Do some
-    'shallow' version of sync safekeepers without data copying? Or just a standard version of
-    sync safekeepers?
-
-## Alternative implementation
-
-The proposal already assumes one of the alternatives -- do not have any persistent storage for
-LFC state. This is possible to implement faster with the proposed API, but it means that
-we do not implement auto-prewarm yet.
-
-## Definition of Done
-
-At the end of implementing this RFC we should have two high-level settings that enable:
-
-1. Auto-prewarm of user computes upon restart.
-2. Perform primary compute restart via the warm replica promotion.
-
-It also has to be decided what's the criteria for enabling one or both of these flows for
-certain clients.
