Besides a simple RETURN NEXT, you'll need to return a SETOF some
composite type. You can do something like

CREATE TYPE twotexts_t AS (txt1 TEXT, txt2 TEXT);

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