Hi,
When v15 docs have:
"27.2.7. Cascading Replication
The cascading replication feature allows a standby server to accept
replication connections and stream WAL records to other standbys, acting
as a relay. This can be used to reduce the number of direct connections
to the primary and also to minimize inter-site bandwidth overheads."
why then, in the release draft, is that capability mentioned as
something that is new for v16?
"
In PostgreSQL 16, users can perform logical decoding from a standby
instance, meaning a standby can publish logical changes to other servers.
"
Is there a difference between the two?
Thanks,
Erik
