Hi All, I get the following error when performing a pg_dump dumping database "ltt"... pg_dump: WARNING: owner of data type trigger appears to be invalid the owner and database exists, I have run the following select statement, select pg_class.oid, pg_trigger.tgrelid from pg_trigger left join pg_class on pg_trigger.tgrelid=pg_class.oid; oid | tgrelid ---------+--------- 1260 | 1260 6081779 | 6081779 6081981 | 6081981 6081779 | 6081779 6081779 | 6081779 6081981 | 6081981 6081975 | 6081975 6081975 | 6081975 6082027 | 6082027 6081779 | 6081779 6081779 | 6081779 6082027 | 6082027 6121607 | 6121607 6121268 | 6121268 6121268 | 6121268 so it appears that it is not a dropped table causing the warning, is there any other way I can try to determine how this warning is being produced, is there a way of viewing the contents of the trigger?
