Great Article! This is also timely for me, I spent all last week deep in the postgres documentation learning about replication (wish I had this article).

I'm building kafka connect (i.e. Debezium) compatible replication:

I really like the mongo change stream API. I think it elegantly hides a lot of the complexity of replication. As a side-effect of building postres -> kafka replication, I'm also trying to build a nicer replication primitive for postgres, that hides some of the underlying replication protocol complexity!
