I can confirm that this bug, introduced in a minor release, is making
pgAdmin look bad, with repeated popup error boxes while viewing user
objects. Grewsome screenshot attached. ;-)
Are we basically leaving pgAdmin in this state until we come up with a
fix and need a new minor release? We pride ourselves in not introducing
breakage in minor releases, but it has certainly happened in this case,
and it is making pgAdmin look bad. Dave, is there a hack you can add to
pgAdmin to work around the join issue until we can fix the backend?
