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.
