Sure: choose their names so that their alphabetical ordering is the
firing order you want. But I see you knew that.

I don't have a lot of sympathy for that argument. If the product is
capable of creating Postgres-compatible triggers at all, it should be
aware that the name is a significant property, and hence provide some
mechanism for selecting a name. Even if it somehow forgot about the
firing-order property, you can't seriously claim that it's our problem
to cater for combinations of client-side code that each think they can
choose trigger names in a vacuum. What if they choose the same name?

This statement lacks content. What problem do you foresee, and what
other ordering rule would you like that doesn't work about as well
as the name rule?
