Postgres 的复制槽是否在跨区域复制中重复？

Question

I have a PostgreSQL DB on Amazon RDS . I need a replication available on a different AWS Region for having high availability. I read the Posgres Docs here . However, I'm not sure if the replication slots are also replicated (along with the lsn's ).

Can someone throw some light on this? Also, if the replication slots are not duplicated on the RDS replica (in the different region), how do I manage a region failure?

Answer 1

In PostgreSQL, replication slots are not replicated. You can, however, create replication slots on standby servers, if you want to use cascading replication.

There is no need to replicate a replication slot.
