Yes ... I don't see a good way to maintain legacy compatibility.
Triggers seem like the least useful place to have variable-argument
functions, though. And it is inconsistent with how we use functions
everywhere else, as well as in violation of the SQL03 standard on CREATE
FUNCTION (don't know what the standard says about triggers, though).
