Amazon RDS for PostgreSQL supports minor versions 16.2, 15.6, 14.11, 13.14, and 12.18

Amazon Relational Database Service (RDS) for PostgreSQL now supports the latest minor versions PostgreSQL 16.2, 15.6, 14.11, 13.14, and 12.18. This release of RDS for PostgreSQL also includes support for pgvector 0.6.0, which adds performance improvements for building Hierarchical Navigable Small Worlds (HNSW) indexes including parallelism and in-memory builds. We recommend that you upgrade to the latest minor versions to fix the known security vulnerabilities in prior versions of PostgreSQL, and to benefit from the bug fixes, performance improvements, and new functionality added by the PostgreSQL community.
