 Bite the bullet and submit the patch to PostgreSQL, to add the t_cid to the WAL records. It makes the WAL records larger, which could make this unpopular in the PostgreSQL community. However, it might simplify some logical decoding code; Andres Freund briefly mentioned in PGCon 2022 discussion on Heikki's Neon presentation that logical decoding currently needs to jump through some hoops to reconstruct the same information.
 
-Update from Heikki (2024-04-17): I tried to write an upstream patch for that, to use the t_cid field for logical decoding, but it was not as straightforward as it first sounded.
 
 ### Alternatives
 Perhaps we could write an extra WAL record with the t_cid information, when a page is evicted that contains rows that were touched a transaction that's still running. However, that seems very complicated.

-This change was made in v16. Starting with v16, when PostgreSQL extends a relation, it first extends
-it with zeros, and it can extend the relation more than one block at a time. The all-zeros page is WAL-ogged, but it's very wasteful to include 8 kB of zeros in the WAL for that. This hack was made so that we WAL logged a compact record with a whole-page "hole". However, PostgreSQL has assertions that prevent that such WAL records from being replayed, so this breaks compatibility such that unmodified PostreSQL cannot process Neon-generated WAL.

-# Graceful Restarts of Storage Controller Managed Clusters
-
-## Summary
-This RFC describes new storage controller APIs for draining and filling tenant shards from/on pageserver nodes.
-It also covers how these new APIs should be used by an orchestrator (e.g. Ansible) in order to implement
-graceful cluster restarts.
-
-## Motivation
-
-Pageserver restarts cause read availablity downtime for tenants.
-
-For example pageserver-3 @ us-east-1 was unavailable for a randomly
-picked tenant (which requested on-demand activation) for around 30 seconds
-during the restart at 2024-04-03 16:37 UTC.
-
-Note that lots of shutdowns on loaded pageservers do not finish within the
-[10 second systemd enforced timeout](https://github.com/neondatabase/infra/blob/0a5280b383e43c063d43cbf87fa026543f6d6ad4/.github/ansible/systemd/pageserver.service#L16). This means we are shutting down without flushing ephemeral layers
-and have to reingest data in order to serve requests after restarting, potentially making first request latencies worse.
-
-This problem is not yet very acutely felt in storage controller managed pageservers since
-tenant density is much lower there. However, we are planning on eventually migrating all
-pageservers to storage controller management, so it makes sense to solve the issue proactively.
-
-## Requirements
-
-- Pageserver re-deployments cause minimal downtime for tenants
-- The storage controller exposes HTTP API hooks for draining and filling tenant shards
-from a given pageserver. Said hooks can be used by an orchestrator proces or a human operator.
-- The storage controller exposes some HTTP API to cancel draining and filling background operations.
-- Failures to drain or fill the node should not be fatal. In such cases, cluster restarts should proceed
-as usual (with downtime).
-- Progress of draining/filling is visible through metrics
-
-## Non Goals
-
-- Integration with the control plane
-- Graceful restarts for large non-HA tenants.
-
-## Impacted Components
-
-- storage controller
-- deployment orchestrator (i.e. Ansible)
-- pageserver (indirectly)
-
-## Terminology
-
-** Draining ** is the process through which all tenant shards that can be migrated from a given pageserver
-are distributed across the rest of the cluster.
-
-** Filling ** is the symmetric opposite of draining. In this process tenant shards are migrated onto a given
-pageserver until the cluster reaches a resonable, quiescent distribution of tenant shards across pageservers.
-
-** Node scheduling policies ** act as constraints to the scheduler. For instance, when a
-node is set in the `Paused` policy, no further shards will be scheduled on it.
-
-** Node ** is a pageserver. Term is used interchangeably in this RFC.
-
-** Deployment orchestrator ** is a generic term for whatever drives our deployments.
-Currently, it's an Ansible playbook.
-
-## Background
-
-### Storage Controller Basics (skip if already familiar)
-
-Fundamentally, the storage controller is a reconciler which aims to move from the observed mapping between pageservers and tenant shards to an intended mapping. Pageserver nodes and tenant shards metadata is durably persisted in a database, but note that the mapping between the two entities is not durably persisted. Instead, this mapping (*observed state*) is constructed at startup by sending `GET location_config` requests to registered pageservers.
-
-An internal scheduler maps tenant shards to pageservers while respecting certain constraints. The result of scheduling is the *intent state*. When the intent state changes, a *reconciliation* will inform pageservers about the new assigment via `PUT location_config` requests and will notify the compute via the configured hook.
-
-### Background Optimizations
-
-The storage controller performs scheduling optimizations in the background. It will
-migrate attachments to warm secondaries and replace secondaries in order to balance
-the cluster out.
-
-### Reconciliations Concurrency Limiting
-
-There's a hard limit on the number of reconciles that the storage controller
-can have in flight at any given time. To get an idea of scales, the limit is
-128 at the time of writing.
-
-## Implementation
-
-Note: this section focuses on the core functionality of the graceful restart process.
-It doesn't neccesarily describe the most efficient approach. Optimizations are described
-separately in a later section.
-
-### Overall Flow
-
-This section describes how to implement graceful restarts from the perspective
-of Ansible, the deployment orchestrator. Pageservers are already restarted sequentially.
-The orchestrator shall implement the following epilogue and prologue steps for each
-pageserver restart:
-
-#### Prologue
-
-The orchestrator shall first fetch the pageserver node id from the control plane or
-the pageserver it aims to restart directly. Next, it issues an HTTP request
-to the storage controller in order to start the drain of said pageserver node.
-All error responses are retried with a short back-off. When a 202 (Accepted)
-HTTP code is returned, the drain has started. Now the orchestrator polls the
-node status endpoint exposed by the storage controller in order to await the
-end of the drain process. When the `policy` field of the node status response
-becomes `PauseForRestart`, the drain has completed and the orchestrator can
-proceed with restarting the pageserver.
-
-The prologue is subject to an overall timeout. It will have a value in the ballpark
-of minutes. As storage controller managed pageservers become more loaded this timeout
-will likely have to increase.
-
-#### Epilogue
-
-After restarting the pageserver, the orchestrator issues an HTTP request
-to the storage controller to kick off the filling process. This API call
-may be retried for all error codes with a short backoff. This also serves
-as a synchronization primitive as the fill will be refused if the pageserver
-has not yet re-attached to the storage controller. When a 202(Accepted) HTTP
-code is returned, the fill has started. Now the orchestrator polls the node
-status endpoint exposed by the storage controller in order to await the end of
-the filling process. When the `policy` field of the node status response becomes
-`Active`, the fill has completed and the orchestrator may proceed to the next pageserver.
-
-Again, the epilogue is subject to an overall timeout. We can start off with
-using the same timeout as for the prologue, but can also consider relying on
-the storage controller's background optimizations with a shorter timeout.
-
-In the case that the deployment orchestrator times out, it attempts to cancel
-the fill. This operation shall be retried with a short back-off. If it ultimately
-fails it will require manual intervention to set the nodes scheduling policy to
-`NodeSchedulingPolicy::Active`. Not doing that is not immediately problematic,
-but it constrains the scheduler as mentioned previously.
-
-### Node Scheduling Policy State Machine
-
-The state machine below encodes the behaviours discussed above and
-the various failover situations described in a later section.
-
-Assuming no failures and/or timeouts the flow should be:
-`Active -> Draining -> PauseForRestart -> Active -> Filling -> Active`

-### Draining/Filling APIs
-
-The storage controller API to trigger the draining of a given node is:
-`PUT /v1/control/node/:node_id/{drain,fill}`.
-
-The following HTTP non-success return codes are used.
-All of them are safely retriable from the perspective of the storage controller.
-- 404: Requested node was not found
-- 503: Requested node is known to the storage controller, but unavailable
-- 412: Drain precondition failed: there is no other node to drain to or the node's schedulling policy forbids draining
-- 409: A {drain, fill} is already in progress. Only one such background operation
-is allowed per node.
-
-When the drain is accepted and commenced a 202 HTTP code is returned.
-
-Drains and fills shall be cancellable by the deployment orchestrator or a
-human operator via: `DELETE /v1/control/node/:node_id/{drain,fill}`. A 200
-response is returned when the cancelation is successful. Errors are retriable.
-
-### Drain Process
-
-Before accpeting a drain request the following validations is applied:
-* Ensure that the node is known the storage controller
-* Ensure that the schedulling policy is `NodeSchedulingPolicy::Active` or `NodeSchedulingPolicy::Pause`
-* Ensure that another drain or fill is not already running on the node
-* Ensure that a drain is possible (i.e. check that there is at least one
-schedulable node to drain to)
-
-After accepting the drain, the scheduling policy of the node is set to
-`NodeSchedulingPolicy::Draining` and persisted in both memory and the database.
-This disallows the optimizer from adding or removing shards from the node which
-is desirable to avoid them racing.
-
-Next, a separate Tokio task is spawned to manage the draining. For each tenant
-shard attached to the node being drained, demote the node to a secondary and
-attempt to schedule the node away. Scheduling might fail due to unsatisfiable
-constraints, but that is fine. Draining is a best effort process since it might
-not always be possible to cut over all shards.
-
-Importantly, this task manages the concurrency of issued reconciles in order to
-avoid drowning out the target pageservers and to allow other important reconciles
-to proceed.
-
-Once the triggered reconciles have finished or timed out, set the node's scheduling
-policy to `NodeSchedulingPolicy::PauseForRestart` to signal the end of the drain.
-
-A note on non HA tenants: These tenants do not have secondaries, so by the description
-above, they would not be migrated. It makes sense to skip them (especially the large ones)
-since, depending on tenant size, this might be more disruptive than the restart since the
-pageserver we've moved to do will need to on-demand download the entire working set for the tenant.
-We can consider expanding to small non-HA tenants in the future.
-
-### Fill Process
-
-Before accpeting a fill request the following validations is applied:
-* Ensure that the node is known the storage controller
-* Ensure that the schedulling policy is `NodeSchedulingPolicy::Active`.
-This is the only acceptable policy for the fill starting state. When a node re-attaches,
-it set the scheduling policy to `NodeSchedulingPolicy::Active` if it was equal to
-`NodeSchedulingPolicy::PauseForRestart` or `NodeSchedulingPolicy::Draining` (possible end states for a node drain).
-* Ensure that another drain or fill is not already running on the node
-
-After accepting the drain, the scheduling policy of the node is set to
-`NodeSchedulingPolicy::Filling` and persisted in both memory and the database.
-This disallows the optimizer from adding or removing shards from the node which
-is desirable to avoid them racing.
-
-Next, a separate Tokio task is spawned to manage the draining. For each tenant
-shard where the filled node is a secondary, promote the secondary. This is done
-until we run out of shards or the counts of attached shards become balanced across
-the cluster.
-
-Like for draining, the concurrency of spawned reconciles is limited.
-
-### Failure Modes & Handling
-
-Failures are generally handled by transition back into the `Active`
-(neutral) state. This simplifies the implementation greatly at the
-cost of adding transitions to the state machine. For example, we
-could detect the `Draining` state upon restart and proceed with a drain,
-but how should the storage controller know that's what the orchestrator
-needs still?
-
-#### Storage Controller Crash
-
-When the storage controller starts up reset the node scheduling policy
-of all nodes in states `Draining`, `Filling` or `PauseForRestart` to
-`Active`. The rationale is that when the storage controller restarts,
-we have lost context of what the deployment orchestrator wants. It also
-has the benefit of making things easier to reason about.
-
-#### Pageserver Crash During Drain
-
-The pageserver will attempt to re-attach during restart at which
-point the node scheduling policy will be set back to `Active`, thus
-reenabling the scheduler to use the node.
-
-#### Non-drained Pageserver Crash During Drain
-
-What should happen when a pageserver we are draining to crashes during the
-process. Two reasonable options are: cancel the drain and focus on the failover
-*or* do both, but prioritise failover. Since the number of concurrent reconciles
-produced by drains/fills are limited, we get the later behaviour for free.
-My suggestion is we take this approach, but the cancellation option is trivial
-to implement as well.
-
-#### Pageserver Crash During Fill
-
-The pageserver will attempt to re-attach during restart at which
-point the node scheduling policy will be set back to `Active`, thus
-reenabling the scheduler to use the node.
-
-#### Pageserver Goes unavailable During Drain/Fill
-
-The drain and fill jobs handle this by stopping early. When the pageserver
-is detected as online by storage controller heartbeats, reset its scheduling
-policy to `Active`. If a restart happens instead, see the pageserver crash
-failure mode.
-
-#### Orchestrator Drain Times Out
-
-Orchestrator will still proceed with the restart.
-When the pageserver re-attaches, the scheduling policy is set back to
-`Active`.
-
-#### Orchestrator Fill Times Out
-
-Orchestrator will attempt to cancel the fill operation. If that fails,
-the fill will continue until it quiesces and the node will be left
-in the `Filling` scheduling policy. This hinders the scheduler, but is
-otherwise harmless. A human operator can handle this by setting the scheduling
-policy to `Active`, or we can bake in a fill timeout into the storage controller.
-
-## Optimizations
-
-### Location Warmth
-
-When cutting over to a secondary, the storage controller will wait for it to
-become "warm" (i.e. download enough of the tenants data). This means that some
-reconciliations can take significantly longer than others and hold up precious
-reconciliations units. As an optimization, the drain stage can only cut over
-tenants that are already "warm". Similarly, the fill stage can prioritise the
-"warmest" tenants in the fill.
-
-Given that the number of tenants by the storage controller will be fairly low
-for the foreseable future, the first implementation could simply query the tenants
-for secondary status. This doesn't scale well with increasing tenant counts, so
-eventually we will need new pageserver API endpoints to report the sets of
-"warm" and "cold" nodes.
-
-## Alternatives Considered
-
-### Draining and Filling Purely as Scheduling Constraints
-
-At its core, the storage controller is a big background loop that detects changes
-in the environment and reacts on them. One could express draining and filling
-of nodes purely in terms of constraining the scheduler (as opposed to having
-such background tasks).
-
-While theoretically nice, I think that's harder to implement and more importantly operate and reason about.
-Consider cancellation of a drain/fill operation. We would have to update the scheduler state, create
-an entirely new schedule (intent state) and start work on applying that. It gets trickier if we wish
-to cancel the reconciliation tasks spawned by drain/fill nodes. How would we know which ones belong
-to the conceptual drain/fill? One could add labels to reconciliations, but it gets messy in my opinion.
-
-It would also mean that reconciliations themselves have side effects that persist in the database
-(persist something to the databse when the drain is done), which I'm not conceptually fond of.
-

-This RFC is accompanied by a POC which implements nearly everything mentioned here
-apart from the optimizations and some of the failure handling:

-# Ancestor Timeline Deletion
-
-Created on: 2024-02-23
-
-Author: John Spray
-
-# Summary
-
-When a tenant creates a new timeline that they will treat as their 'main' history,
-it is awkward to permanently retain an 'old main' timeline as its ancestor. Currently
-this is necessary because it is forbidden to delete a timeline which has descendents.
-
-A new pageserver API is proposed to 'adopt' data from a parent timeline into
-one of its children, such that the link between ancestor and child can be severed,
-leaving the parent in a state where it may then be deleted.
-
-# Motivation
-
-Retaining parent timelines currently has two costs:
-
-- Cognitive load on users, who have to remember which is the "real" main timeline.
-- Storage capacity cost, as the parent timeline will retain layers up to the
-  child's timeline point, even if the child fully covers its keyspace with image
-  layers and will never actually read from the parent.
-
-# Solution
-
-A new pageserver API `PUT /v1/tenant/:tenant_id/timeline/:timeline_id/detach_ancestor`
-will be added. The `timeline_id` in this URL is that of the _child_ timeline that we
-wish to detach from its parent.
-
-On success, this API will leave the following state:
-
-- The detached child timeline will no longer have an ancestor, and will contain all
-  the data needed to service reads without recursing into an ancestor.
-- Any other children of the parent whose timeline points were at a lower LSN than
-  the detached child timeline will be modified to have the child timeline as their
-  new parent.
-- The parent timeline will still exist, but the child will no longer have it as an
-  ancestor. If this was the last timeline that depended on the parent, then the
-  parent will become deletable.
-
-This API's implementation will consist of a series of retryable steps, such that
-on failures/timeout it can safely be called again to reach the target state.
-
-## Example
-
-### Before
-
-The user has "rolled back" their project to LSN X, resulting in a "new main"
-timeline. The parent "old main" timeline still exists, and they would like
-to clean it up.
-
-They have two other timelines A and B. A is from before the rollback point,
-and B is from after the rollback point.
-
-```
-----"old main" timeline-------X-------------------------------------------->
-                |             |                         |
-                |-> child A   |                         |
-                              |-> "new main" timeline   |
-                                                        -> child B
-
-```
-
-### After calling detach ancestor API
-
-The "new main" timeline is no longer dependent on old main, and neither
-is child A, because it had a branch point before X.
-
-The user may now choose to delete child B and "old main" to get to
-a pristine state. Child B is likely to be unwanted since the user
-chose to roll back to X, and it branches from after X. However, we
-don't assume this in the API; it is up to the user to delete it.
-
-```
-|----"old main" timeline---------------------------------------------------->
-                                                         |
-                                                         |
-                                                         |
-                                                         -> child B
-
-|----"new main" timeline--------->
-                 |
-                 |-> child A
-
-
-```
-
-### After removing timelines
-
-We end up with a totally clean state that leaves no trace that a rollback
-ever happened: there is only one root timeline.
-
-```
-| ----"new main" timeline----------->
-                |
-                |-> child A
-
-
-```
-
-## Caveats
-
-Important things for API users to bear in mind:
-
-- this API does not delete the parent timeline: you must still do that explicitly.
-- if there are other child timelines ahead of the branch point of the detached
-  child, the parent won't be deletable: you must either delete or detach those
-  children.
-- do _not_ simply loop over all children and detach them all: this can have an
-  extremely high storage cost. The detach ancestor API is intended for use on a single
-  timeline to make it the new "main".
-- The detach ancestor API should also not be
-  exposed directly to the user as button/API, because they might decide
-  to click it for all the children and thereby generate many copies of the
-  parent's data -- the detach ancestor API should be used as part
-  of a high level "clean up after rollback" feature.
-
-## `detach_ancestor` API implementation
-
-Terms used in the following sections:
-
-- "the child": the timeline whose ID is specified in the detach ancestor API URL, also
-  called "new main" in the example.
-- "the parent": the parent of "the child". Also called "old main" in the example.
-- "the branch point" the ancestor_lsn of "the child"
-
-### Phase 1: write out adopted layers to S3
-
-The child will "adopt" layers from the parent, such that its end state contains
-all the parent's history as well as its own.
-
-For all layers in the parent's layer map whose high LSN is below the branch
-point, issue S3 CopyObject requests to duplicate them into the child timeline's
-prefix. Do not add them to the child's layer map yet.
-
-For delta layers in the parent's layer map which straddle the branch point, read them
-and write out only content up to the branch point into new layer objects.
-
-This is a long running operation if the parent has many layers: it should be
-implemented in a way that resumes rather than restarting from scratch, if the API
-times out and is called again.
-
-As an optimization, if there are no other timelines that will be adopted into
-the child, _and_ the child's image layers already full cover the branch LSN,
-then we may skip adopting layers.
-
-### Phase 2: update the child's index
-
-Having written out all needed layers in phase 1, atomically link them all
-into the child's IndexPart and upload to S3. This may be done while the
-child Timeline is still running.
-
-### Phase 3: modify timelines ancestry
-
-Modify the child's ancestor to None, and upload its IndexPart to persist the change.
-
-For all timelines which have the same parent as the child, and have a branch
-point lower than our branch point, switch their ancestor_timeline to the child,
-and upload their IndexPart to persist the change.
-
-## Alternatives considered
-
-### Generate full image layer on child, rather than adopting parent deltas
-
-This would work for the case of a single child, but would prevent re-targeting
-other timelines that depended on the parent. If we detached many children this
-way, the storage cost would become prohibitive (consider a 1TB database with
-100 child timelines: it would cost 100TiB if they all generated their own image layers).
-
-### Don't rewrite anything: just fake it in the API
-
-We could add a layer of indirection that let a child "pretend" that it had no
-ancestor, when in reality it still had the parent. The pageserver API could
-accept deletion of ancestor timelines, and just update child metadata to make
-them look like they have no ancestor.
-
-This would not achieve the desired reduction in storage cost, and may well be more
-complex to maintain than simply implementing the API described in this RFC.
-
-### Avoid copying objects: enable child index to use parent layers directly
-
-We could teach IndexPart to store a TimelineId for each layer, such that a child
-timeline could reference a parent's layers directly, rather than copying them
-into the child's prefix.
-
-This would impose a cost for the normal case of indices that only target the
-timeline's own layers, add complexity, and break the useful simplifying
-invariant that timelines "own" their own path. If child timelines were
-referencing layers from the parent, we would have to ensure that the parent
-never runs GC/compaction again, which would make the API less flexible (the
-proposal in this RFC enables deletion of the parent but doesn't require it.)
-
-## Performance
-
-### Adopting layers
-
-- CopyObject is a relatively cheap operation, but we may need to issue tens of thousands
-  of such requests: this can take up to tens of seconds and will compete for RemoteStorage
-  semaphore units with other activity on the pageserver.
-- If we are running on storage backend that doesn't implement CopyObject, then
-  this part will be much more expensive as we would stream all layer content
-  through the pageserver. This is no different to issuing a lot
-  of reads to a timeline that does not have a warm local cache: it will move
-  a lot of gigabytes, but that shouldn't break anything.
-- Generating truncated layers for delta that straddle the branch point will
-  require streaming read/write of all the layers in question.
-
-### Updating timeline ancestry
-
-The simplest way to update timeline ancestry will probably be to stop and start
-all the Timeline objects: this is preferable to the complexity of making their
-ancestry mutable at runtime.
-
-There will be a corresponding "stutter" in the availability of the timelines,
-of the order 10-100ms, which is the time taken to upload their IndexPart, and
-restart the Timeline.
-
-# Interaction with other features
-
-## Concurrent timeline creation
-
-If new historic timelines are created using the parent as an ancestor while the
-detach ancestor API is running, they will not be re-parented to the child. This
-doesn't break anything, but it leaves the parent in a state where it might not
-be possible to delete it.
-
-Since timeline creations are an explicit user action, this is not something we need to
-worry about as the storage layer: a user who wants to delete their parent timeline will not create
-new children, and if they do, they can choose to delete those children to
-enable deleting the parent.
-
-For the least surprise to the user, before starting the detach ancestor branch
-operation, the control plane should wait until all branches are created and not
-allow any branches to be created before the branch point on the ancestor branch
-while the operation is ongoing.
-
-## WAL based disaster recovery
-
-WAL based disaster recovery currently supports only restoring of the main
-branch. Enabling WAL based disaster recovery in the future requires that we
-keep a record which timeline generated the WAL and at which LSN was a parent
-detached. Keep a list of timeline ids and the LSN in which they were detached in
-the `index_part.json`. Limit the size of the list to 100 first entries, after
-which the WAL disaster recovery will not be possible.
-
-## Sharded tenants
-
-For sharded tenants, calls to the detach ancestor API will pass through the storage
-controller, which will handle them the same as timeline creations: invoke first
-on shard zero, and then on all the other shards.
