Well, if the dependent objects don't need to be touched because the
view's API (its output column set) isn't changing, then you can use
CREATE OR REPLACE VIEW.
If the output column set *is* changing, you need to redefine all the
dependent objects anyway. Oracle may be willing to guess at what
should happen to them, but Postgres isn't.
