The core server package shouldn't have any python dependency. It doesn't surprise me so much that the contrib package does, though. Most likely, that includes the plpython transform modules (hstore_plpython, jsonb_plpython, etc), which are certainly going to depend on whichever libpython PG was built with. It might've been better to split out those modules as a separate package. OTOH that would add confusion, and we have a lot of subpackages already. Another idea might be to bundle them into the plpython package instead of contrib (and similarly for the plperl transforms). regards, tom lane
