Dedicated replica PgBouncers
We've just released the ability to provision dedicated PgBouncers for your Postgres replicas. Dedicated PgBouncers run on nodes separate from Postgres.
This allows you to have a connection pool that will evenly distribute connections across your available replicas, making it simple to scale out read-only traffic by using your two included replicas or even scaling out more by adding additional replicas to your Postgres cluster.
