As it happens it does not; the issue came up originally because of a
hack I came up with, and I've never used any pg version so old it didn't
have CREATE OR REPLACE VIEW. Nor does it look like the change was ever
backpatched (or at least not that far).

Of course, at the time I myself didn't think of using a view rather than
a table for the initial creation; I was focused on rules because that
was the only way to get updateable views then. So arguably it is at
least partly my fault.

Certainly.
