Thx, Tom. OpenSUSE's most recent postgres 9.1 is 9.1.6. Yet, 9.1.1 is what was part of the opensuse12.1 snapshot of RPMs on top of which some of our engineers develop proprietary apps. It worked well for them to freeze an RPM repo because it can happen (and did happen!) that upgrading an individual RPM snow-balled due to package dependencies and eventually broke a proprietary app. It's unfortunate timing that 9.1.1 was the version at the time of the freeze. So, I guess, one needs to evaluate to what extent an upgrade of postgres is contained (e.g. nothing else but perl-DBD::Pg) OR weigh the effort against building it from source.
