If so, you're probably running out of memory for the list of pending trigger events (to verify that the FK constraint isn't violated by the delete). Allowing the triggers to fire individually would take forever anyway, so it might be best to drop the foreign key constraint(s) and then re-establish them after the delete. regards, tom lane
