You don't need to create any type for trigger procedures. From inside of
trigger procedure You can acces two rows(tuples): NEW and OLD, and Your
trigger function must RETURN NEW if you want to allow data changes, or OLD if
You want to discard changes.
Also, this is more pgsql-hackers(at)postgresql(dot)org kind of question...
