Please, use the following runbook.
1. Disable the subscription to pg10.
2. Disable Application Users on Publisher.
3. Drop all replication slots on Publisher (The upgrade can not be executed
if there are any replication slots)
4. Run RDS's upgrade (which runs pg_upgrade).
5. Recreate replication
I also am realizing belatedly that my solution of dropping the subscriber
probably won't work anyway, since I'd lose the changes on the publisher for
