Oh, well if that's the case, that is great news. But then I don't
understand Amit's comment from before:

I believe that (b) is the correct behavior, so I assumed that this
issue must be some difficulty in implementing it, like a funny catalog
representation.
Things might be clearer if we'd made the syntax "ALTER PUBLICATION p1
{ ADD | DROP } { TABLE | SCHEMA } name". I don't understand why we
used this ALL TABLES IN SCHEMA language.
