Schema vs Namespace

What's the strategy for naming things schema or namespace? In notice that
pg_dump messages are all about namespaces. That seems confusing from a
user's viewpoint.

Probably the user-visible messages should all mention schemas.

I named the catalog pg_namespace because I didn't want to nail down
a presumption that the things in it are exactly equivalent to SQL
schemas; namespaces are an implementation mechanism to support schemas,
but not necessarily an equivalent concept. But this bit of
implementation philosophy isn't very relevant for users.
