The following does work ... (does the refcursor get closed automatically
in this example?)


CREATE OR REPLACE FUNCTION x(
BIGINT
)
RETURNS BIGINT AS '
DECLARE
    type_id_p ALIAS FOR $1;
    type_rc_v REFCURSOR;
BEGIN
    OPEN type_rc_v FOR SELECT * FROM type
        WHERE type_id = type_id_p;

    RETURN xxx(type_rc_v);
END;
' LANGUAGE 'plpgsql' WITH (isstrict);

CREATE OR REPLACE FUNCTION xxx(
REFCURSOR
)
RETURNS BIGINT AS '
DECLARE
    type_rc_p ALIAS FOR $1;
    type_row_v type%ROWTYPE;
BEGIN
    FETCH type_rc_p INTO type_row_v;

    IF type_row_v.type_id IS NULL THEN
        RETURN -2;
    END IF;

    RETURN type_row_v.type_kind;
END;
' LANGUAGE 'plpgsql' WITH (isstrict);
