I'm worried that an approach based on postgres_fdw would have security
problems. I think that we don't want postgres_fdw installed in every
PostgreSQL cluster for security reasons. And I think that the set of
people who should be permitted to manage connection strings for
logical replication subscriptions could be different from the set of
people who are entitled to use postgres_fdw.
