Nightly has added a bunch of compiler and linter warnings. There is also
two dependencies that fail compilation on latest nightly due to using
the old `stdsimd` feature name. This PR fixes them.
instead of direct S3 request.
Pros:
- simplify code a lot (no need to provide AWS credentials and paths);
- reduce latency of downloading extension data as proxy resides near
computes; -reduce AWS costs as proxy has cache and 1000 computes asking
the same extension will not generate 1000 downloads from S3.
- we can use only one S3 bucket to store extensions (and rid of regional
buckets which were introduced to reduce latency);
Changes:
- deprecate remote-ext-config compute_ctl parameter, use
http://pg-ext-s3-gateway if any old format remote-ext-cofig is provided;
- refactor tests to use mock http server;
- trivial serialization roundtrip test for
`pageserver::repository::Value`
- add missing `start_paused = true` to 15s test making it <0s test
- completely unrelated future clippy lint avoidance (helps beta channel
users)
This adds PostgreSQL 16 as a vendored postgresql version, and adapts the
code to support this version.
The important changes to PostgreSQL 16 compared to the PostgreSQL 15
changeset include the addition of a neon_rmgr instead of altering Postgres's
original WAL format.

Don't download ext_index.json from s3, but instead receive it as a part of spec from control plane.
This eliminates s3 access for most compute starts,
and also allows us to update extensions spec on the fly
Add infrastructure to dynamically load postgres extensions and shared libraries from remote extension storage.
Before postgres start downloads list of available remote extensions and libraries, and also downloads 'shared_preload_libraries'. After postgres is running, 'compute_ctl' listens for HTTP requests to load files.
Postgres has new GUC 'extension_server_port' to specify port on which 'compute_ctl' listens for requests.
When PostgreSQL requests a file, 'compute_ctl' downloads it.
See more details about feature design and remote extension storage layout in docs/rfcs/024-extension-loading.md
