This is a great resource. The PG docs are generally quite good, but logical replication is one of those things where experience and this sort of resource is invaluable. That said, I also feel like logical replication is still pretty hard to use. One example, not covered here, is that the status of slots is not replicated to any secondaries. There are solutions for this now (see https://www.percona.com/blog/how-patroni-addresses-the-problem-of-the-logical-replication-slot-failover-in-a-postgresql-cluster/ https://www.percona.com/blog/how-patroni-addresses-the-probl...) but generally the domain of dealing with logical changes is still one where I feel like MySQL binlog has a leg up (though still some sharp edges) in making it a bit easier to work with.
