This is a bug tracker
If you have a question, such has "how do you do X with Python/PostgreSQL/psycopg2" please write to the mailing list or open a question instead.

Before opening this ticket, please confirm that:

• I am running the latest version of pip, i.e. typing pip --version you get this version.
• I have read the installation documentation and the frequently asked questions
• If install failed, I typed pg_config on the command line and I obtained an output instead of an error.

Please complete the following information:

• OS: Windows 10
• Psycopg version: 2.9.5
• Python version: 3.8.0
• PostgreSQL version: N/A
• pip version: 22.3

Installation of psycopg2-binary 2.9.4 works correctly, as expected. Installation of 2.9.5 throws the following error:

      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>).

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