7.2.1: pg_dump of UNIONed VIEWs broken

PostgreSQL 7.2.1's pg_dump prduces bad SQL for VIEW's.

The SQL for CREATE VIEW as output by pg_dump generates an error, because the
appropriate nesting of SELECTs with parentheses is missing:
ERROR: parser: parse error at or near "SELECT"


Original SQL:

CREATE VIEW "agents" as (
        (
        SELECT DISTINCT
                employees.contact_id
        FROM
                employees
        ORDER BY
                employees.contact_id
        )
UNION
        (
        SELECT DISTINCT
                contractors.contact_id
        FROM
                contractors
        ORDER BY
                contractors.contact_id
        )
);


As output by pg_dump:

CREATE VIEW "agents" as SELECT DISTINCT employees.contact_id FROM employees
ORDER BY employees.contact_id UNION SELECT DISTINCT contractors.contact_id
FROM contractors ORDER BY contractors.contact_id;

As you can see, the nesting is entirely lost.
