## Problem
Extension tests were previously run sequentially, resulting in
unnecessary wait time and underutilization of available CPU cores.
## Summary of changes
Tests are now executed in a customizable number of parallel threads
using separate database branches. This reduces overall test time by
approximately 50% (e.g., on my laptop, parallel test lasts 173s, while
sequential one lasts 340s) and increases the load on the pageserver,
providing better test coverage.

## Problem
Previously, the background worker that collects the list of installed
extensions across DBs had a timeout set to 1 hour. This cause a problem
with computes that had a `suspend_timeout` > 1 hour as this collection
was treated as activity, preventing compute shutdown.
Issue: https://github.com/neondatabase/cloud/issues/30147
## Summary of changes
Passing the `suspend_timeout` as part of the `ComputeSpec` so that any
updates to this are taken into account by the background worker and
updates its collection interval.
## Problem
The `computed_columns` test assumes that computed columns are always
faster than the request itself. However, this is not always the case on
Neon, which can lead to flaky results.
## Summary of changes
The `computed_columns` test is excluded from the PostGIS test for
PostgreSQL v16, accompanied by related patch refactoring.
## Problem
The script `compute.sh` had a non-consistent coding style and didn't
follow best practices for modern bash scripts
## Summary of changes
The coding style was fixed to follow best practices.
## Problem
We don't currently run tests for PostGIS in our test environment.
## Summary of Changes
- Added PostGIS test support for PostgreSQL v16 and v17
- Configured different PostGIS versions based on PostgreSQL version:
- PostgreSQL v17: PostGIS 3.5.0
- PostgreSQL v14/v15/v16: PostGIS 3.3.3
- Added necessary test scripts and configurations
This ensures our PostgreSQL implementation remains compatible with this
widely-used extension.

## Problem
The regression test for the extension online_advisor fails on the

## Problem
The regression test on extensions relied on the admin API to set the
default endpoint settings, which is not stable and requires admin
privileges. Specifically:
- The workflow was using `default_endpoint_settings` to configure
necessary PostgreSQL settings like `DateStyle`, `TimeZone`, and
`neon.allow_unstable_extensions`
- This approach was failing because the API endpoint for setting
`default_endpoint_settings` was changed (referenced in a comment as
issue #27108)
- The admin API requires special privileges.
## Summary of changes
We get rid of the admin API dependency and use ALTER DATABASE statements
instead:
**Removed the default_endpoint_settings mechanism:**
- Removed the default_endpoint_settings input parameter from the
neon-project-create action
- Removed the API call that was attempting to set these settings at the
project level
- Completely removed the default_endpoint_settings configuration from
the cloud-extensions workflow
**Added database-level settings:**
- Created a new `alter_db.sh` script that applies the same settings
directly to each test database
- Modified all extension test scripts to call this script after database
creation
The first line in /etc/ld.so.conf is:
/etc/ld.so.conf.d/*
We want to control library load order so that our compiled binaries are
picked up before others from system packages. The previous solution
allowed the system libraries to load before ours.

This PR adds a runtime validation mode to check adherence to alignment
and size-multiple requirements at the VirtualFile level.
This can help prevent alignment bugs from slipping into production
because test systems may have more lax requirements than production.
(This is not the case today, but it could change in the future).
It also allows catching O_DIRECT bugs on systems that don't have
O_DIRECT (macOS).
Consequently, we can now accept
`virtual_file_io_mode={direct,direct-rw}` on macOS now.
This has the side benefit of removing some annoying conditional
compilation around `IoMode`.
A third benefit is that it helped weed out size-multiple requirement
violation bugs in how the VirtualFile unit tests exercise read and write
APIs.
I seized the opportunity to trim these tests down to what actually
matters, i.e., exercising of the `OpenFiles` file descriptor cache.
Lastly, this PR flips the binary-built-in default to `DirectRw` so that
when running Python regress tests and benchmarks without specifying
`PAGESERVER_VIRTUAL_FILE_IO_MODE`, one gets the production behavior.

## Problem
We had retained the ability to run in a generation-less mode to support
test_generations_upgrade, which was replaced with a cleaner backward
compat test in https://github.com/neondatabase/neon/pull/10701
## Summary of changes
- Remove all the special cases for "if no generation" or "if no control
plane api"
- Make control_plane_api config mandatory

## Problem
We currently don't run end-to-end tests for PostgreSQL extensions on our
cloud infrastructure, which means we might miss problems that only occur
in a real cloud environment.
## Summary of changes
- Added a workflow to run extension tests against a cloud staging
instance
- Set up proper project configuration for extension testing
- Implemented test execution with appropriate environment settings
- Added error handling and reporting for test failures

## Problem
The docker compose test script (`docker_compose_test.sh`) had
inconsistent codestyle, mixing legacy syntax with modern approaches and
not following best practices at all. This inconsistency could lead to
potential issues with variable expansion, path handling, and
maintainability.
## Summary of changes
This PR modernizes the test script with several codestyle improvements:
* Variable scoping and exports:
* Added proper export declarations for environment variables
* Added explicit COMPOSE_PROFILES export to avoid repetitive flags
* Modern Bash syntax:
* Replaced [ ] with [[ ]] for safer conditional testing
* Used arithmetic operations (( cnt += 3 )) instead of expr
* Added proper variable expansion with braces ${variable}
* Added proper quoting around variables and paths with "${variable}"
* Docker Compose commands:
* Replaced hardcoded container names with service names
* Used docker compose exec instead of docker exec $CONTAINER_NAME
* Removed repetitive flags by using environment variables
* Shell script best practices:
* Added function keyword before function definition
* Used safer path handling with "$(dirname "${0}")"
These changes make the script more maintainable, less error-prone, and
more consistent with modern shell scripting standards.
These various hacks were needed for the forward compatibility tests.
Enough time has passed since the merge that these are no longer needed.

Previously, the structure of the spec file was just the compute spec.
However, the response from the control plane get spec request included
the compute spec and the compute_ctl config. This divergence was
hindering other work such as adding regression tests for compute_ctl
HTTP authorization.

## Problem
Some extensions do not contain tests, which can be easily run on top of
docker-compose or staging.
## Summary of changes
Added the pg_regress based tests for `pg_tiktoken`, `pgx_ulid`, `pg_rag`
Now they will be run on top of docker-compose, but I intend to adopt
them to be run on top staging in the next PRs
## Problem
Docker Hub has new rate limits coming up, and to avoid problems coming
with those we're switching to GHCR.
## Summary of changes
- Push images to GHCR initially and distribute them from there
- Use images from GHCR in docker-compose
## Problem
We have not synced `force-test-extensions-upgrade.yml` with the last
changes.
The variable `TEST_EXTENSIONS_UPGRADE` was ignored in the script and
actually set to `NEW_COMPUTE_TAG` while it should be set to
`OLD_COMPUTE_TAG` as we are about to run compatibility tests.
## Summary of changes
The tag names were synced, the logic was fixed.
## Problem
CI does not pass for the compute release due to the absence of some
images
## Summary of changes
Now we use the images from the old non-compute releases for non-compute
images
## Problem
We created extensions in a single database. The tests could interfere,
i.e., discover some service tables left by other extensions and produce
unexpected results.
## Summary of changes
The tests are now run in a separate timeline, so only one extension owns
the database, which prevents interference.
## Problem
Release CI is slow, because we're doing unnecessary work, for example
building compute images on storage releases and vice versa.
## Summary of changes
- Extract tag generation into reusable workflow and extend it with
fetching of previous component releases
- Don't build neon images on compute releases and don't build compute
images on proxy and storage releases
- Reuse images from previous releases for tests on branches where we
don't build those images
## Open questions
- We differentiate between `TAG` and `COMPUTE_TAG` in a few places, but
we don't differentiate between storage and proxy releases. Since they
use the same image, this will continue to work, but I'm not sure this is
what we want.
## Problem
The patch for `semver` extensions relies on `PG_VERSION` environment
variable. The files were named without the letter `v` so script cannot
find them.
## Summary of changes
The patch files were renamed.
## Problem
We use `docker cp` to copy the files required for the extension tests
now.
It causes problems if we run older images with the newer source tree.
## Summary of changes
Copying the files was moved to the compute Dockerfile.
## Problem
The nightly test discovered problems in the extensions upgrade test.
1. `PLv8` has different versions on PGv17 and PGv16 and a different test
set, which was not implemented correctly
[sample](https://github.com/neondatabase/neon/actions/runs/13382330475/job/37372930271)
2. The same for `semver`
[sample](https://github.com/neondatabase/neon/actions/runs/13382330475/job/37372930017)
3. `pgtap` interfered with the other tests, e.g. tables, created by
other extensions caused the tests to fail.
## Summary of changes
The discovered problems were fixed.
1. The tests list for `PLv8` is now generated using the original
Makefile
2. The patches for `semver` are now split for PGv16 and PGv17.
3. `pgtap` is being tested in a separate database now.

## Problem
We run the compatibility tests only if we are upgrading the extension.
An accidental code change may break the test itself, so we have to check
this code as well.
## Summary of changes
The test is scheduled once a day to save time and resources.

## Problem
The upgrade test for pg_jwt does not work correctly.
## Summary of changes
The script for the upgrade test is modified to use the database
`contrib_regression`.
## Problem
We have to test the extensions, shipped with Neon for compatibility
before the upgrade.
## Summary of changes
Added the test for compatibility with the upgraded extensions.
## Problem
The containers' log output is mixed with the tests' output, so you must
scroll up to find the error.
## Summary of changes
Printing of containers' logs moved to a separate step.
## Problem
The trust connection to the compute required for `pg_anon` was removed.
However, the PGPASSWORD environment variable was not added to
`docker-compose.yml`.
This caused connection errors, which were interpreted as success due to
errors in the bash script.
## Summary of changes
The environment variable was added, and the logic in the bash script was
fixed.
## Problem
We are removing the `pg_anon` v1 extension from Neon. So we don't need
to test it anymore and can remove the code for simplicity.
## Summary of changes
The code required for testing `pg_anon` is removed.
## Problem
It's impossible to run docker compose with compute v17 due to `pg_anon`
extension which is not supported under PG17.
## Summary of changes
The auto-loading of `pg_anon` is disabled by default
## Problem
The extensions for Postgres v17 are ready but we do not test the
extensions shipped with v17
## Summary of changes
Build the test image based on Postgres v17. Run the tests for v17.
