U could try this:
CREATE OR REPLACE FUNCTION stat() RETURNS refcursor AS '
DECLARE
ref refcursor;
---------
change 4:
---------
CREATE OR REPLACE FUNCTION stat(refcursor) RETURNS refcursor AS '
DECLARE
cursor ALIAS FOR $1;
ref refcursor;
sport=# BEGIN;
sport=# select stat(cursor);
sport=# fetch all in cursor;
sport=# END;
It works fine with me!!!
