Post the code you have an a usuage example makes it alot easier to
understand what you are doing.
See manual
http://www.postgresql.org/docs/8.1/interactive/plpgsql-cursors.html#PLPGSQL-CURSOR-USING
CREATE TABLE table_1 (c1 varchar(10));
INSERT INTO table_1
SELECT 'some text1';
INSERT INTO table_1
SELECT 'some text2';
select * from table_1
CREATE OR REPLACE FUNCTION myfunc(refcursor) RETURNS SETOF refcursor AS $$
BEGIN
OPEN $1 FOR SELECT * FROM table_1;
RETURN NEXT $1;
END;
$$ LANGUAGE plpgsql;
-- need to be in a transaction to use cursors.
BEGIN;
SELECT * FROM myfunc('a');
FETCH ALL FROM a;
COMMIT;
