Your query is the same as select sum(pg_relation_size(oid, 'main')) from pg_class; I bet you'll find that the difference is accounted for by one of select sum(pg_relation_size(oid, 'fsm')) from pg_class; select sum(pg_relation_size(oid, 'vm')) from pg_class; Drill down and see which table is responsible ... regards, tom lane -- Sent via pgsql-admin mailing list (pgsql-admin@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-admin
