Output function

Hi!

This is some function.

CREATE FUNCTION my_func(text) RETURNS text AS '
   DECLARE
     name TEXT;
     lastname TEXT;
   BEGIN
     name := ''Uros'';
     lastname := ''Gruber'';
     RETURN ime;
   END;
' LANGUAGE 'plpgsql';

Output is like this

 my_func
--------
 Uros
(1 row)

What i want to do is output like this


   name     |        lastname
------------+------------------
   uros     |         gruber
(1 row)

How can i write this function to return both values?
