[Python] I am trying to install psycopg2 or psycopg2-binary in my venv on MacOS X

I keep getting those errors

(env) macbook@MACBOOKs-MacBook-Pro server % pip3 install psycopg2-binary

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>).
