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.
