dev-python/psycopg: Bump to 2.7.3.2 and many fixes

Apply a couple patches. One for building documentation (634730) and
another to avoid building against mxdatetime from the antiquated
dev-python/egenix-mx-base (452028, 629430).

This version knows how to parse the new PostgreSQL version scheme
(625540).

Docs build again (540996).
