Hi, I'm starting to become desperate. On saturday I dumped all databases, wiped whole postgresql installation. Installed newest rpms for Fedora 1, restored databases. Recompiled client libraries and binaries. Restarted and after five hours of operation: May 1 21:34:19 claymountain postgres[6337]: [2-1] ERROR: could not access status of transaction 4250811410 May 1 21:34:19 claymountain postgres[6337]: [2-2] DETAIL: could not open file "/var/lib/pgsql/data/pg_clog/0FD5": No such file or directory Is there anything else I could do than dump, wipe, restore again? Isn't there anything I could do to try to get more detailed meaningful information on why this is happening? All that the log shows before this happening are a few unexpected client disconnections.
