Description: STATEMENT_TIMEOUT DOES NOT WORK PROPERLY

Details:

Hi, i use PostgreSQL 8 Beta4.I write a sf like that :
/////////
CREATE OR REPLACE FUNCTION fn_test()
RETURNS "varchar" AS
$BODY$
DECLARE
c refcursor;
r record;
BEGIN
SET SESSION STATEMENT_TIMEOUT = 1000;
OPEN C FOR SELECT * FROM T_KULLANICILAR FOR UPDATE;
FETCH C INTO R;
RESET STATEMENT_TIMEOUT;
RETURN '1';
EXCEPTION
WHEN QUERY_CANCELED THEN
RAISE EXCEPTION 'UNABLE TO OBTAIN LOCK... :%';
END;
$BODY$
LANGUAGE 'plpgsql' VOLATILE;
/////////
1.I RUN A THIS "SELECT * FROM T_KULLANICILAR FOR UPDATE" from another
session to lock T_KULLANICILAR table rows.
2.While T_KULLANICILAR table was locked,i called sf like "SELECT FN_TEST()"
from psql command prompt.But STATEMENT_TIMEOUT doesn't effect.
3.but i enter "SET SESSION STATEMENT_TIMEOUT = 1000;" command before step 2,
STATEMENT_TIMEOUT affects and cancel query.
