## 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
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
staging instance due to a lack of permission to alter the database.
## Summary of changes
A script was added to work around this problem.

## Problem
We didn't test the h3 extension in our test suite.
## Summary of changes
Added tests for h3 and h3-postgis extensions
Includes upgrade test for h3

## 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
## 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
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
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
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
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
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.
