Amazon Relational Database Service (RDS) Proxy now supports PostgreSQL major version 15. PostgreSQL 15 includes new features such as the SQL standard "MERGE" command for conditional SQL queries, performance improvements for both in-memory and disk-based sorting, support for two-phase commit, and row/column filtering for logical replication. The PostgreSQL 15 release also adds support for server-side compression with Gzip, LZ4, or Zstandard (zstd) using pg_basebackup. For more details about this release, refer to the PostgreSQL community announcement. You can also enforce SCRAM (Salted Challenge Response Authentication Mechanism) password-based authentication for your proxy.
