Обсуждение: PG 10 logical replication version dependency?

Hi,

Is there a version dependency when using logical replication? Do both
sides have to be running the same major version? Or is it a wire
protocol that will be backwards compatible in future releases?

I sincerely hope it's the latter so that users of this aren't forced
to upgrade all of their interconnected servers at the same time.

Thanks,

Colin

I think the only restriction is that connected servers need to be Postgres 10 or higher. 

So you should be able to replicate from Postgres 10 to Postgres 11 once the next version is released.
