No, in this case the procedure is a trigger procedure and is not
supposed to be called directly at all. But we don't have a
distinguishable signature for triggers as yet. One of the changes
I'd like to make eventually is that trigger procs take and return
some special pseudo-type, so that the type system can catch this
sort of mistake explicitly.
