I don't see any problem with extending pg_upgrade to use logical
replication features under the covers.

It seems very smooth to be able to just say

   pg_upgrade --online

and then specify whatever other parameters that requires.

It would be much easier to separate out that as a use-case so we can be
sure we get that in 10.0, even if nothing else lands.
