Works for me:
regression=# SELECT i AS "PK_ID", d AS "Deleted" FROM ( SELECT 52 AS i, true AS d ) x ORDER BY i;PK_ID | Deleted

regression=# SELECT i AS "PK_ID", d AS "Deleted" FROM ( SELECT 49 AS i, true AS d UNION SELECT 51 AS i, true AS d ) x
ORDERBY i;PK_ID | Deleted
-------+--------- 49 | t 51 | t
(2 rows)
