I think I'm current on 9.2.5 / CentOs 6.4.

Don't know if this is useful information, but I was surprised that the
problem continues even wrapping the view as a subquery, and then even if
the subquery has a client_id IS NOT NULL clause:
ag_spc=> SELECT foo.client_id AS foo_id,boo.client_id AS
ri_id,move_in_type,annual_income,monthly_income_total,dependent_count FROM
(SELECT -1 AS client_id) foo LEFT OUTER JOIN (SELECT * FROM rent_info WHERE
client_id IS NOT NULL) boo USING (client_id);
foo_id | ri_id | move_in_type | annual_income | monthly_income_total |
dependent_count
--------+-------+--------------+---------------+----------------------+-----------------
-1 | | Move-in | 0 | 0 |
0
(1 row)
I'm happy to provide whatever additional information is helpful--just let
me know. Thanks.
