I read somewhere that it was possible to have a replication on an Upgraded major version I believe by using logical replication?
Not sure myself, but was hoping there is a way as our application required some debugging after the upgrade due to improper concatenation of SQL statements that was not enforced in PGSQL-12.
Thanks

Hi Frank
Streaming/Physical Replication requires that both Master and Standby are using the same OS and same PG major version.
