Amazon Relational Database Service (RDS) Proxy now supports Amazon Aurora with PostgreSQL-compatibile edition and Amazon RDS for PostgreSQL running major version 14. PostgreSQL 14 consists of performance improvements for parallel queries, heavily-concurrent workloads, partitioned tables, logical replication, and vacuuming. PostgreSQL 14 also improves functionality with new capabilities. For example, you can cancel long-running queries if a client disconnects and you can close idle sessions if they time out. With this launch, you can enforce SCRAM (Salted Challenge Response Authentication Mechanism ) password-based authentication for proxy, making connections from your applications more secure.
