Thanks Ralph. I think that worked. I made the changes you suggested, but after that the OpenERP database names seemed to get screwed up and trying to log into my development database kept resulting in an incorrect login error. I tried logging in with admin/admin and that worked, but the database it was logging me into was another one that I had created with just the demo data in it. I had done a full backup of the development database before upgrading PostgreSQL so I dropped all the existing databases and restored the backup. I could then log in to it as normal.
