Target customers: ApsaraDB RDS for PostgreSQL users. Features released: an ApsaraDB RDS for PostgreSQL instance with standard SSD or enhanced SSD now allows you to create multiple read-only instances and configure drivers such as JDBC driver and libpq driver to enable load balancing on the session layer. If the driver you use does not support load balancing on the session layer, you can use Server Load Balancer (SLB) to balance read loads among read-only instances. If you want to enable the read/write splitting feature, you can install the open source PostgreSQL read/write splitting proxy Pgpool-II on an ECS instance.
