The PostgreSQL RPM packages for SUSE have been neglected a bit recently. I have put up some packages for 8.3.0 and 8.3.1 at the
openSUSE Build Service. Use the
search interface to search for "postgresql". This won't be a permanent project of mine, but I'll probably continue as long as I need the packages myself and SUSE or someone else doesn't organize this job more sustainably.
