junk=# \d baz
View "public.baz"
Column | Type | Modifiers
--------+-----------+-----------
a | "unknown" |
b | "unknown" |
View definition:
SELECT 'hello' AS a, 'world' AS b;
There is no table behind the view, so there is no way for PostgreSQL to
derive the column types of a and b. A quoted string (as supplied in the
view definition) could be one of text, varchar, char, date, time,
timestamp, cidr and so on.
