plpgsql function returning SETOF RECORD Question

Hi

When I run the function below I recieve an error message saying that column definitions need to be specified for a function returing a type RECORD.

I was under the impression that the FOR row IN SELECT... loop would assign a column structure to the RECORD type. Am I wrong about this?

CREATE FUNCTION test() RETURNS SETOF RECORD AS '
DECLARE
row RECORD;
BEGIN
FOR row IN SELECT * FROM dates LOOP
RETURN NEXT row;
END LOOP;

RETURN;
END;
' LANGUAGE 'plpgsql';

PostgreSQL 7.3.2-3 on Red Hat 9.

Regards

John Duffy
