If you have sufficient enough rights on the database you can modify the
triggers in whatever way you deem fit. There is currently no alternative
way to specify trigger execution order than alphabetically.

I guess such re-naming could introduce problems with applications but that
is unlikely.

Note, too, that you can leave but disable the existing triggers and define
your own triggers with whatever name you require and simply call the same
function as the existing trigger.

Is this a theoretical question or do you actual have this problem?
