      Error: pg_config executable not found.

      pg_config is required to build psycopg2 from source.  Please add the directory
      containing pg_config to the $PATH or specify the full executable path with the
      option:

          python setup.py build_ext --pg-config /path/to/pg_config build ...

      or with the pg_config option in 'setup.cfg'.

      If you prefer to avoid building psycopg2 from source, please install the PyPI
      'psycopg2-binary' package instead.

      For further information please check the 'doc/src/install.rst' file (also at
      <https://www.psycopg.org/docs/install.html>).

Does it make sense to increase version? https://github.com/sclorg/django-ex/blob/2.2.x/requirements.txt#L4

[phracek]

Adding these three packages libpg-devel, gcc, python3.12-devel solves the problem, but I guess this is not the right approach.

[phracek]

I guess, this file https://github.com/sclorg/django-ex/blob/2.2.x/requirements.txt should be modified so it is able to consume as version 3.11 as version 3.12.

[frenzymadness]

Container image with Python 3.12 should not use Django 2.2.x with the old psycopg-binary package. That's the reason why we implemented this: #731

Where is the definition telling the test to use 2.2.x branch for Python 3.12? We should fix it as we did it in the mentioned PR.

[phracek]

Here: https://github.com/sclorg/s2i-python-container/blob/master/test/test-lib-python.sh#L100. I will fix it. Thanks good point.
