## Problem
We want to have a number of custom extensions that will not be available
by default, as an example of such is [Postgres
Anonymizer](https://postgresql-anonymizer.readthedocs.io/en/stable/)
(please note that the extension should be added to
`shared_preload_libraries`). To distinguish them, custom extensions
should be added to a different S3 path:
```
s3://<bucket>/<release version>/<postgres_version>/<ext_name>/share/extensions/
s3://<bucket>/<release version>/<postgres_version>/<ext_name>/lib
where <ext_name> is an extension name
```
Resolves https://github.com/neondatabase/neon/issues/4582
## Summary of changes
- Add Postgres Anonymizer extension to Dockerfile (it's included only to
postgres-extensions target)
- Build extensions image from postgres-extensions target in a workflow
- Upload custom extensions to S3 (different directory)
## Problem
We want to store Postgres Extensions in S3 (resolves
https://github.com/neondatabase/neon/issues/4493).
Proposed solution:
- Create a separate docker image (from scratch) that contains only
extensions
- Do not include extensions into compute-node (except for neon
extensions)*
- For release and main builds upload extract extension from the image
and upload to S3 (`s3://<bucket>/<release
version>/<postgres_version>/...`)**
*) We're not doing it until the feature is not fully implemented
**) This differs from the initial proposal in
https://github.com/neondatabase/neon/issues/4493 of putting extensions
straight into `s3://<bucket>/<postgres_version>/...`, because we can't
upload directory atomicly. A drawback of this is that we end up with
unnecessary copies of files ~2.1 GB per release (i.e. +2.1 GB for each
commit in main also). We don't really need to update extensions for each
release if there're no relevant changes, but this requires extra work.
## Summary of changes
- Created a separate stage in Dockerfile.compute-node
`postgres-extensions` that contains only extensions
- Added a separate step in a workflow that builds `postgres-extensions`
image (because of a bug in kaniko this step is commented out because it
takes way too long to get built)
- Extract extensions from the image and upload files to S3 for release
and main builds
- Upload extenstions only for staging (for now)
Doc says that it should be added into `shared_preload_libraries`, but,
practically, it's not required.

## Describe your changes
Compiles kq_imcx extension
At this moment, there are some issues with the extension:
1. I'm cloning it directly from the master branch. It's better to fetch
tag/archive
2. PG14:
```
postgres=# CREATE EXTENSION IF NOT EXISTS kq_imcx;
postgres=# select * from kq_calendar_cache_info();
2023-02-08 13:55:22.853 UTC [412] ERROR: relation "ketteq.slice_type" does not exist at character 34
2023-02-08 13:55:22.853 UTC [412] QUERY: select min(s.id), max(s.id) from ketteq.slice_type s
2023-02-08 13:55:22.853 UTC [412] STATEMENT: select * from kq_calendar_cache_info();
ERROR: relation "ketteq.slice_type" does not exist
LINE 1: select min(s.id), max(s.id) from ketteq.slice_type s
```
3. PG15:
`cannot request additional shared memory outside shmem_request_hook`
Note: I don't think we need to publish info about this extension in the
docs.

neondatabase/cloud#3387
To not be taken by surprise by upstream git re-tag or by malicious activity,
let's verify the checksum for extensions we download
Also, unify the installation of `pg_graphql` and `pg_tiktoken`
with other extensions.
After enabling autoscaling, we faced the issue that customers are not
able to get the number of CPUs they use at this moment. Therefore I've
added these two options:
1. Postgresql function to allow customers to call it whenever they want
2. `compute_ctl` endpoint to show these number in console
Recently added `unsafe-postgres` feature allows to build pgx extensions
against postgres forks that decided to change their ABI name (like us).
With that we can build extensions without forking them and using stock
pgx. As this feature is new few manual version bumps were required.
## Describe your changes
Layer for building pg extensions written on Rust
It required forking:
* `cargo-pgx` (in order not to catch an ABI mismatch error (`cargo-pgx`
hardcoded ABI tcdi/pgx#1032)
* `pg_jsonschema` (to use forked `cargo-pgx` version)
* `pgx-contrib-spiext` (to use forked `cargo-pgx`)
* `pg_graphql` (to use forked `cargo-pgx` and `pgx-contrib-spiext`
version)
Before the patch:
```
postgres=# create extension pg_jsonschema;
2023-02-02 17:45:23.120 UTC [35] ERROR: incompatible library "/usr/local/lib/pg_jsonschema.so": ABI mismatch
2023-02-02 17:45:23.120 UTC [35] DETAIL: Server has ABI "Neon Postgres", library has "PostgreSQL".
2023-02-02 17:45:23.120 UTC [35] STATEMENT: create extension pg_jsonschema;
ERROR: incompatible library "/usr/local/lib/pg_jsonschema.so": ABI mismatch
DETAIL: Server has ABI "Neon Postgres", library has "PostgreSQL".
```
After
```
postgres=# create extension pg_jsonschema;
CREATE EXTENSION
postgres=# select json_matches_schema('{"type": "object"}', '{}');
json_matches_schema
---------------------
t
postgres=# create extension pg_graphql;
CREATE EXTENSION
postgres=# create table book(id int primary key, title text);
CREATE TABLE
postgres=# insert into book(id, title) values (1, 'book 1');
INSERT 0 1
postgres=# select graphql.resolve($$
query {
bookCollection {
edges {
node {
id
}
}
}
}
$$);

`pg_jsonschema` extension will be available for our customers
after executing
```sql
CREATE EXTENSION unit;
```
I saw such error
```

* Add submodule postgres-15
* Support pg_15 in pgxn/neon
* Renamed zenith -> neon in Makefile
* fix name of codestyle check
* Refactor build system to prepare for building multiple Postgres versions.
Rename "vendor/postgres" to "vendor/postgres-v14"
Change Postgres build and install directory paths to be version-specific:
- tmp_install/build -> pg_install/build/14
- tmp_install/* -> pg_install/14/*
And Makefile targets:
- "make postgres" -> "make postgres-v14"
- "make postgres-headers" -> "make postgres-v14-headers"
- etc.
Add Makefile aliases:
- "make postgres" to build "postgres-v14" and in future, "postgres-v15"
- similarly for "make postgres-headers"
Fix POSTGRES_DISTRIB_DIR path in pytest scripts
* Make postgres version a variable in codestyle workflow
* Support vendor/postgres-v15 in codestyle check workflow
* Support postgres-v15 building in Makefile
* fix pg version in Dockerfile.compute-node
* fix kaniko path
* Build neon extensions in version-specific directories
* fix obsolete mentions of vendor/postgres
* use vendor/postgres-v14 in Dockerfile.compute-node.legacy
* Use PG_VERSION_NUM to gate dependencies in inmem_smgr.c
* Use versioned ECR repositories and image names for compute-node.
The image name format is compute-node-vXX, where XX is postgres major version number.
For now only v14 is supported.
Old format unversioned name (compute-node) is left, because cloud repo depends on it.
* update vendor/postgres submodule url (zenith->neondatabase rename)
* Fix postgres path in python tests after rebase
* fix path in regress test
* Use separate dockerfiles to build compute-node:
Dockerfile.compute-node-v15 should be identical to Dockerfile.compute-node-v14 except for the version number.
This is a hack, because Kaniko doesn't support build ARGs properly
* bump vendor/postgres-v14 and vendor/postgres-v15
* Don't use Kaniko cache for v14 and v15 compute-node images
* Build compute-node images for different versions in different jobs

Slim down compute-node images:
- Optimize compute_ctl build for size, not performance & debug-ability
- Don't run unused stages. Saves time in not building the PLV8 extension.
- Do not include static libraries in clean postgres
- Do the installation and finishing touches in the final layer in one job
This allows docker (and kaniko) to only register one change to the files,
removing potentially duplicate changed files.
- The runtime library for libreadline-dev is libreadline8, changing the dependency saves 45 MB
- libprotobuf-c-dev -> libprotobuf-c1, saving 100 kB
- libossp-uuid-dev -> libossp-uuid16, saving 150 kB
- gdal-bin + libgdal-dev -> libgeos-c1v5 + libgdal28 + libproj19, saving 747MB
- binutils @ testing -> libc6 @ testing, saving 32 MB
Update PLV8 to 3.1.4 - which is the latest release.
Update PostGIS to 3.3.0
Remove PLV8 from the final image -- there is an issue we hit when installing PLV8, and we don't quite know what it is yet.
