display cursor contents

I wish to display the output of a cursor but haven't discovered the trick.
Here's what I'm doing:

-- The function

CREATE OR REPLACE FUNCTION tmp.sps(character varying, date)
RETURNS refcursor AS
$BODY$
DECLARE
ref refcursor;
BEGIN
OPEN ref FOR select * from tmp.sps_measurement where logdate < $2;
RETURN ref;
END;
$BODY$
LANGUAGE 'plpgsql' VOLATILE;

-- psql script expected to display the contents of the cursor

BEGIN;

declare
ref cursor for select tmp.sps('=','2006-06-12') ;

FETCH all IN ref;
commit;

-- Output:

xxx z=# \i sps_test.sql
BEGIN
DECLARE CURSOR
sps
--------------------
<unnamed portal 9>
(1 row)

(I am expecting the rows in the tmp.sps_measurement table.) Can anyone
help me out with this?
