Concur on this. I always thought that Debezium only supported MySQL binlog since that is the world I operate in. I did not know that it was also an option for Postgres CDC via the WAL. Now that I know, I would recommend defaulting to it.

Even with Debezium I have run into myriad issues. It blows my mind that someone would want to roll their own logic to set up replicas. IMHO this post should be advertised more as a fun intellectual exercise.
