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).
