SETOF is not for returning multiple columns, it is for returning
multiple *rows*. I don't think that's what you want here.
Returning multiple columns requires a tuple (structure) return datatype.
Unfortunately that's not supported all that well right now. Check the
pgsql archives for my message about functions returning tuples, from a
few days back.
