refcursor returned by pl/psql to jdbc - Mailing list pgsql-general

Ok, I wanted to wrap a select statement with a PL/pgsql procedure
(information hiding, etc.)
So I have:

CREATE OR REPLACE FUNCTION user_data_select_all(BIGINT)
RETURNS REFCURSOR AS '
DECLARE
    -- parameters
    owner_id_p ALIAS FOR $1;

    -- local variables
    rc REFCURSOR;
BEGIN
    OPEN rc FOR SELECT *
        FROM user_data
        WHERE
            owner_id = owner_id_p;
    RETURN rc;
END;
' LANGUAGE 'plpgsql' WITH (isstrict);

Now from within psql I get the following:

=> select user_data_select_all(12);
 user_data_select_all
----------------------
 <unnamed cursor 15>
(1 row)

I kind of expected to see the actual rows?!?

and from JDBC I get an exception:
Bad Long <unnamed cursor 1>
        at org.postgresql.jdbc2.ResultSet.toLong(ResultSet.java:1498)
        at org.postgresql.jdbc2.ResultSet.getLong(ResultSet.java:257)

So the question is can I wrap a select function as return a resultset to
JDBC?
