Yes, it works a lot better in 8.2: http://archives.postgresql.org/pgsql-committers/2006-08/msg00222.php If you really need the right output type in 8.1, you could force the issue with an extra level of sub-select: regression=# create table foo (f1 varchar(8)); CREATE TABLE regression=# create view voo as select f1::varchar(8) from (select * from foo union select * from foo) ss; CREATE VIEW regression=# \d voo View "public.voo" Column | Type | Modifiers --------+----------------------+----------- f1 | character varying(8) | View definition: SELECT ss.f1::character varying(8) AS f1 FROM ( SELECT foo.f1 FROM foo UNION SELECT foo.f1 FROM foo) ss; regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 5: don't forget to increase your free space map settings
