Exactly. The defaults attached to the underlying table determine what
gets added to an INSERT into the underlying table. In this case, since
the rule's INSERT specifies all the fields, there is no scope for those
defaults to apply.
What Berend actually wants is to attach column defaults to the *view*,
so that they apply to an INSERT mentioning the view. You can do this in
recent PG releases (7.3 for sure, not sure about 7.2) using ALTER TABLE
... ADD DEFAULT.
