As you may already know, Postgres will stop supporting v11 and we are using a version of it. The upgrade in the AWS end is quite straight forward but there is a few points that I don't understand.
-We are using logical replication from Application database into this Postgres v11 database, will this upgrade break it? In documentation here, if I understand correctly it should not break it. Since our database is subscriber, it does not have a replication slot.
-What will happen to endpoint? I don't fully understand that if host information is going to change or not.
-And latest point, we have also a read replica for this database, will this upgrade affect that one? From the documentation that I share, I kinda get mixed signals.
