## 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
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 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.
