And, if the user wants it to be run first, he or she can do that.  But
suppose he wants to run it first, and also forbid users whose username
starts with the letter b from running the ANALYZE command.  Well,
then, he now wants that trigger to come before the other one, even
though the Slony trigger is for all commands (maybe) and the other
just for ANALYZE (maybe).
