You forgot to open the cursor.
regression=# CREATE OR REPLACE FUNCTION test(integer,integer) RETURNS REFCURSOR AS '

regression'# test cursor for SELECT * from tenk1;
regression'# begin

regression'# RETURN test;
regression'# END;' LANGUAGE 'plpgsql';
CREATE
regression=# begin;
BEGIN
regression=# select test(4,5);

regression=# fetch forward 1 from test;

I dunno why plpgsql is defined to need an OPEN for a cursor, but it is.
