-# Supporting custom user Extensions (Dynamic Extension Loading)
-Created 2023-05-03
-
-## Motivation
-
-There are many extensions in the PostgreSQL ecosystem, and not all extensions
-are of a quality that we can confidently support them. Additionally, our
-current extension inclusion mechanism has several problems because we build all
-extensions into the primary Compute image: We build the extensions every time
-we build the compute image regardless of whether we actually need to rebuild
-the image, and the inclusion of these extensions in the image adds a hard
-dependency on all supported extensions - thus increasing the image size, and
-with it the time it takes to download that image - increasing first start
-latency.
-
-This RFC proposes a dynamic loading mechanism that solves most of these
-problems.
-
-## Summary
-
-`compute_ctl` is made responsible for loading extensions on-demand into
-the container's file system for dynamically loaded extensions, and will also
-make sure that the extensions in `shared_preload_libraries` are downloaded
-before the compute node starts.
-
-## Components
-
-compute_ctl, PostgreSQL, neon (extension), Compute Host Node, Extension Store
-
-## Requirements
-
-Compute nodes with no extra extensions should not be negatively impacted by
-the existence of support for many extensions.
-
-Installing an extension into PostgreSQL should be easy.
-
-Non-preloaded extensions shouldn't impact startup latency.
-
-Uninstalled extensions shouldn't impact query latency.
-
-A small latency penalty for dynamically loaded extensions is acceptable in
-the first seconds of compute startup, but not in steady-state operations.
-
-## Proposed implementation
-
-### On-demand, JIT-loading of extensions
-
-Before postgres starts we download 
-- control files for all extensions available to that compute node;
-- all `shared_preload_libraries`;
-
-After postgres is running, `compute_ctl` listens for requests to load files.
-When PostgreSQL requests a file, `compute_ctl` downloads it.
-
-PostgreSQL requests files in the following cases:
-- When loading a preload library set in `local_preload_libraries`
-- When explicitly loading a library with `LOAD`
-- Wnen creating extension with `CREATE EXTENSION` (download sql scripts, (optional) extension data files and (optional) library files)))
-
-
-#### Summary
-
-Pros:
- - Startup is only as slow as it takes to load all (shared_)preload_libraries
- - Supports BYO Extension
-
-Cons:
- - O(sizeof(extensions)) IO requirement for loading all extensions.
-
-### Alternative solutions
-
-1. Allow users to add their extensions to the base image
-   
-   Pros:
-    - Easy to deploy
-
-   Cons:
-    - Doesn't scale - first start size is dependent on image size;
-    - All extensions are shared across all users: It doesn't allow users to
-      bring their own restrictive-licensed extensions
-
-2. Bring Your Own compute image
-   
-   Pros:
-    - Still easy to deploy
-    - User can bring own patched version of PostgreSQL
-
-   Cons:
-    - First start latency is O(sizeof(extensions image))
-    - Warm instance pool for skipping pod schedule latency is not feasible with
-      O(n) custom images
-    - Support channels are difficult to manage
-
-3. Download all user extensions in bulk on compute start
-   
-   Pros:
-    - Easy to deploy
-    - No startup latency issues for "clean" users.
-    - Warm instance pool for skipping pod schedule latency is possible
-
-   Cons:
-    - Downloading all extensions in advance takes a lot of time, thus startup
-      latency issues
-
-4. Store user's extensions in persistent storage
-   
-   Pros:
-    - Easy to deploy
-    - No startup latency issues
-    - Warm instance pool for skipping pod schedule latency is possible
-
-   Cons:
-    - EC2 instances have only limited number of attachments shared between EBS
-      volumes, direct-attached NVMe drives, and ENIs.
-    - Compute instance migration isn't trivially solved for EBS mounts (e.g.
-      the device is unavailable whilst moving the mount between instances).
-    - EBS can only mount on one instance at a time (except the expensive IO2
-      device type).
-
-5. Store user's extensions in network drive
-   
-   Pros:
-    - Easy to deploy
-    - Few startup latency issues
-    - Warm instance pool for skipping pod schedule latency is possible
-
-   Cons:
-    - We'd need networked drives, and a lot of them, which would store many
-      duplicate extensions.
-    - **UNCHECKED:** Compute instance migration may not work nicely with
-      networked IOs
-
-
-### Idea extensions
-
-The extension store does not have to be S3 directly, but could be a Node-local
-caching service on top of S3. This would reduce the load on the network for
-popular extensions.
-
-## Extension Storage implementation
-
-Extension Storage in our case is an S3 bucket with a "directory" per build and postgres version,
-where extension files are stored as plain files in the bucket following the same directory structure as in the postgres.
-
-i.e.
-
-`s3://<the-bucket>/<build-version>/<postgres-version>/lib/postgis-3.1.so`
-`s3://<the-bucket>/<build-version>/<postgres-version>/share/extension/postgis.control`
-`s3://<the-bucket>/<build-version>/<postgres-version>/share/extension/postgis--3.1.sql`
-
-To handle custom extensions, that available only to specific users, we use per-extension subdirectories:
-
-i.e.
-`s3://<the-bucket>/<build-version>/<postgres-version>/<custom-ext-prefix>/lib/ext-name.so`, etc.
-`s3://<the-bucket>/<build-version>/<postgres-version>/<custom-ext-prefix>/share/extension/ext-name.control`, etc.
-
-On compute start, `compute_ctl` accepts a list of custom_ext_prefixes.
-
-To get the list of available extensions,`compute_ctl` downloads control files from all prefixes:
-
-`s3://<the-bucket>/<build-version>/<postgres-version>/share/extension/`
-`s3://<the-bucket>/<build-version>/<postgres-version>/<custom-ext-prefix1>/share/extension/`
-`s3://<the-bucket>/<build-version>/<postgres-version>/<custom-ext-prefix2>/share/extension/`
-
-
-
-### How to add new extension to the Extension Storage?
-
-Simply upload build artifacts to the S3 bucket.
-Implement a CI step for that. Splitting it from ompute-node-image build.
-
-### How do we deal with extension versions and updates?
-
-Currently, we rebuild extensions on every compute-node-image build and store them in the <build-version> prefix.
-This is needed to ensure that `/share` and `/lib` files are in sync.
-
-For extension updates, we rely on the PostgreSQL extension versioning mechanism (sql update scripts) and extension authors to not break backwards compatibility within one major version of PostgreSQL.
-
-### Alternatives
-
-For extensions written on trusted languages we can also adopt
-`dbdev` PostgreSQL Package Manager based on `pg_tle` by Supabase.
-This will increase the amount supported extensions and decrease the amount of work required to support them.
