Autovacuum and pg_largeobject

  Hi all

I would like to know if the large object table pg_largeobject is
routinely checked by the autovacuum daemon.
I ask about this because I have a database in wich the pg_largeobject
table is being forcibly vacuumed because it's relfrozenxid is now
greater than autovacuum_freeze_max_age, and it's killing the server
performance. PostgreSQL version is 8.2.14.

Thanks
