Ah, then I've been misled. I grepped my source and SETS_FIXED is never
defined. If you read the source and some of the (hard to find) docs
regarding the SETOF operator you run into comments like "this probably
doesn't work" and the like. It looked like the SETOF operations were
being handled by the code under SETS_FIXED hence my original question.
