Are you saying that psycopg2 needs setuptools for the setup.py script
to work? This isn't generally the case (or wasn't), but maybe the
"entry point" is a setuptools thing which would then demand that
software's presence.

How does stdeb know which package provides psycopg2? I'm not really
familiar with stdeb - I write my own packaging files - but might it be
the case that you need to specify python-psycopg2 instead?
