Multi-column returns from pgsql

Hi Everyone,

Does anyone know if/how it's possible to return multi-column sets from a pgsql 
function?  Right now I'm using something like the following as a work around

CREATE OR REPLACE FUNCTION my_func() returns SETOF TEXT AS '
DECLARE   rec record;
BEGIN   FOR rec IN SELECT txt1, txt2 FROM mytable LOOP      RETURN NEXT rec.txt1;      RETURN NEXT rec.txt2;   END
LOOP;  RETURN;
 
END;' language 'plpgsql';

which leaves me parsing multiple records to achieve the desired end result.

Anyone have any thoughts?

Thanks,
Mark
