I'm not sure I agree. There are explicit triggers for update, insert, and
delete, therefor why not also have a trigger for replace? It is one more
case. Rather than try to figure out how to map replace into two distinct
behaviors of insert or update based on some conditional logic, why not just
have a replace trigger?
