## Problem
Currently, we run the `pg_regress` tests only for PG16
However, PG17 is a part of Neon and should be tested as well
## Summary of changes
Modified the workflow and added a patch for PG17 enabling the
`pg_regress` tests.
The problem with leftovers was solved by using branches.
## 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.

## Problem
Current compute images for Postgres 14-16 don't build on Debian 12
because of issues with extensions.
This PR fixes that, but for the current setup, it is mostly a no-op
change.
## Summary of changes
- Use `/bin/bash -euo pipefail` as SHELL to fail earlier
- Fix `plv8` build: backport a trivial patch for v8
- Fix `postgis` build: depend `sfgal` version on Debian version instead
of Postgres version
Tested in: https://github.com/neondatabase/neon/pull/9849
## Problem
The Postgres version was updated. The patch has to be updated
accordingly.
## Summary of changes
The patch of the regression test was updated.
## Problem
All the other patches were moved to the compute directory, and only one
was left in the patches subdirectory in the root directory.
## Summary of changes
The patch was moved to the compute directory as others
Seems nice to keep all these together. This also provides a nice place
for a README file to describe the compute image build process. For
now, it briefly describes the contents of the directory, but can be
expanded.
