Note that if those processes use persistent connections you'll need to restart them to free up the connections. In the meantime you can use the step of renaming your superuser account. Then cutting all superuser conns and turning off superuser of postgres user temporarily. I wouldn't do this all night or anything, as autovac usually connects as postgres to do its thing. -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
