I don't think there's much cause for concern here. If my theory is correct, this is an autovacuum bug which was fixed in 8.1.7. What I'd do is create a 0207 clog file, fill it with 0x55 (which is "transactions committed" for all transactions in that interval), and do a VACUUM FREEZE on that database. You'll need to set pg_database.datallowconn=true beforehand. Of course, I'd copy the files somewhere else and experiment on a scratch postmaster, running on a different port, just to be sure ... -- Alvaro Herrera http://www.CommandPrompt.com/ The PostgreSQL Company - Command Prompt, Inc. ---------------------------(end of broadcast)--------------------------- TIP 5: don't forget to increase your free space map settings
