> Perhaps postgres allows listening to the replication log with lower latency?
Yes, I think that's what the "logical decoding" referred to. Postgres can emit a "logical" version of the WAL (something with a stable spec writtten down so that other services can stream and decode it). My understanding was that "logical replication" was designed for low latency situations like creating read replicas.
I haven't heard of the logical log being preserved for "years back" but that's an interesting case...
