Fixed version is attached. I've tried to rerun the 'archie' benchmark with the current patch, and once again I got PANIC: could not split GIN page, didn't fit I reran it with '--enable-cassert' and with that I got TRAP: FailedAssertion("!(ginCompareItemPointers(&items[i - 1], &items[i]) < 0)", File: "gindatapage.c", Line: 149) LOG: server process (PID 5364) was terminated by signal 6: Aborted DETAIL: Failed process was running: INSERT INTO messages ... so the assert in GinDataLeafPageGetUncompressed fails for some reason. I can easily reproduce it, but my knowledge in this area is rather limited so I'm not entirely sure what to look for. regards Tomas -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
