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).
