You are wrong. It means you cannot simply alter a replicated table on
the origin and have it altered automatically on the replica (but you can
do it with some manual labour). If you want to replicate a new set of
tables, you can do that easily.

I imagine you've already been flamed to death about the one-schema-per-user
bit so I won't say anything about that.
