Seems very useful. This stuff can’t be done already with pg replication?

I think it’s targeted at [many -> one] database consolidation versus Postgres replication which is more suited for [one -> one]. I’m sure you can do [many -> one] with just Postgres and some shenanigans but it’s probably quite Rube Goldberg. Also in Postgres <16 you can’t replica of replica, using a CDC tool to pipe data around you don’t have that restriction.

It also takes care of setting up publications, replication slots and the initial sync.
