same issue here when trying to pip install psycopg2 for python3.8. The error I see is this:

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>).
[end of output]
note: This error originates from a subprocess, and is likely not a problem with pip.

Similar issue for me on Ubuntu 24.04 for python 3.10 (and install works on python 3.12) when running uv pip install psycopg2 :

It appears you are missing some prerequisite to build the package from source.
You may install a binary package by installing 'psycopg2-binary' from PyPI.
If you want to install psycopg2 from source, please install the packages
required for the build and try again.
For further information please check the 'doc/src/install.rst' file (also at
<https://www.psycopg.org/docs/install.html>).
