When installing the requirements via "pip install -r requirements.txt" after activating the venv, I get the below error.

I was able to fix it following the advice of https://stackoverflow.com/questions/35104097/how-to-install-psycopg2-with-pg-config-error, but it'd be handy if it worked "out of the box", e.g. if this could be added as a dependency.

      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>).

  note: This error originates from a subprocess, and is likely not a problem with pip.

As said in the error, use and "pip install psycopg2-binary" and remove "psycopg2-binary==2.8.5" from the requirement.txt

I appreciate that the error message says to do that, but my point is that the requirements.txt should be valid if this is a consistent error.
