A question : is there any way for my application code to transparently "recognize" that (at runtime) there is a new follower PG database that is assigned to the application and that it should route some of the reads to the new follower DB? Or do I have to manually change my app's db configuration and include the new follower's address? Does Postgres actually natively support this and is there any client library that makes use of that? I know that Zookeeper serves this sort of purpose (automatic service discovery etc.), but I have no idea whether/how it works with Postgres.
