Обсуждение: cache lookup failed
I am relatively new to postgres, and am struggling with the following, I am trying to set up a trigger on a table that deletes the foreign key references in the child table, I'm executing the delete command in the usual way (assuming already connected)- delete from website where website_id = '$website_id'; which works fine when there is no trigger on the table but once the trigger is created I get the following error - fmgr_info: function 47172: cache lookup failed Has anyone seen a similar problem, any help would be greatly appreciated. Cheers Graham

The full definitions of both tables and the trigger function would help. Also, what version are you using? regards, tom lane
