Subject: Getting the return type right for SETOF

Hi folks,

I'm playing with SETOF on functions.  But I can't get the return type 
correct.  What have I missed?  A cast?

CREATE OR REPLACE FUNCTION elementGet (text) RETURNS SETOF 
element_type AS '

select 1,
       \'test\',
       \'F\'
       \'A\',
       FALSE,
       FALSE
'
    LANGUAGE sql stable;
ERROR:  function declared to return element_type returns "unknown" 
instead of text at column 2

\d element_type
Composite type "public.element_type"
   Column   |  Type
------------+---------
 id         | integer
 name       | text
 type       | text
 status     | text
 iscategory | boolean
 isport     | boolean
