      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

      ).
