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 -------+--------- 52 | t (1 row) 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 ORDER BY i; PK_ID | Deleted -------+--------- 49 | t 51 | t (2 rows) regression=# What PG version are you using, exactly? regards, tom lane
