There was also some changes to the core that should be implemented but we were waiting for PG to catch up with things. Search the forum. Also note that acs-person was deprecated, I updated my instances but never submitted patches as PG until 7.3 didn't support dropping columns and keeping RI intact.
Hope this makes sense, if not blame the home brew!
