+1 This is in the right direction. The resolution rules and catalog APIs need more discussion when we implement it.
In the current stage, we can disallow the runtime creation of the catalog. This will complicate the name resolution in a multi-session environment. For example, when one user creates a catalog in one session, the other users' queries might return different results because the tables are differently resolved. We might need to investigate how the other systems deal with this.
