You might also confirm that the directory $PGDATA/pg_twophase/ is empty, but it really should be if there's nothing in that view. I think you'll have to do some more sleuthing. Check the pg_database.datfrozenxid value for the "maindb" database, then look in pg_class for the table(s) with that same value for pg_class.relfrozenxid. Vacuum these table(s) individually. Do their relfrozenxid values change? regards, tom lane -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
