I too am experiencing the same problem, but at least in my case, I cannot modify anything in request tracker (e.g even new requests cannot be submitted)
After some investigation, it appears that a change in postgresql 7.3 (converting between null/empty values and (int)0 in pg_atoi) is the cause of the problem - see http://rt3.fsck.com/Ticket/Display.html?id=2143 and http://marc.theaimsgroup.com/?l=rt-devel&m=104582491029719&w=2 as well as the postgresql release notes. A subsequent version of request-tracker has been released which addresses this problem, but it is a later version than is available in sarge/sid. I believe that this problem makes request-tracker unusable as it stands in sarge/testing (this bug should probably be promoted to a serious issue, but I'll leave that to the package maintainers/others). It would be good if a newer version could be packaged; this would also close #186202 thanks
