I guess I am missing the point of COMMUTATOR then. The docs say "When
you are defining a self-commutative operator, you just do it." It
seems you need to do more than "just do it." As far as I can tell I
will need to add another C function and another CREATE OPERATOR.
Then I can create an operator that takes args (text, chkpass) instead
of (chkpass, text). What is the COMMUTATOR for then? Is it just a
hint to the planner?
