You realize, I hope, that 8.1 has been out of support for more than six years. > The VACUUM FULL command seems to get stuck on vacuuming > "pg_catalog.pg_largeobject" (last message for Verbose) If that table is very large --- check with, eg, select pg_size_pretty(pg_relation_size('pg_largeobject')); then VACUUM FULL is going to take a heck of a long time, particularly with the old implementation that was used in 8.1. But if your objective is to return disk space to the OS, you may not have much choice; plain VACUUM doesn't try very hard to do that. > Error message reads as follows: > ERROR: out of memory > DETAIL: Failed on request of size 134217728. I'm assuming that you are saying that VACUUM FULL fails with that, which is not what "getting stuck" seems to mean otherwise. If that happens to be equal to your current maintenance_work_mem setting, you could probably dodge the problem by reducing maintenance_work_mem. That would make it even slower :-( but at least you'd have hope of completing eventually. Personally I'd think very hard about going the dump-and-restore route and updating to a somewhat modern version of Postgres while you're at it. There are an awful lot of known bugs in 8.1, even assuming that you're on the last minor release 8.1.23. Updating to an OS that's still supported by its maker would be a bright move as well. regards, tom lane -- Sent via pgsql-hackers mailing list (email@example.com) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
