    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>).
