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

view definition) could be one of text, varchar, char, date, time,
timestamp, cidr and so on.
