Review comment:
> We should set back to the default namespace of the current catalog. Not
sure we have such a command yet, cc @imback82
No, we don't have a such a command yet. Do you think it will be useful to
have one?
This also reminds me about the behavior of dropping namespace. If you are
trying to drop a namespace, which is set to the current namespace, this
shouldn't be allowed right? We don't have a such a check yet, but I can add one
if needed.
