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.

You are able to leverage automatic minor version upgrades to automatically upgrade your databases to more recent minor versions during scheduled maintenance window. Learn more about upgrading your database instances and extended support in the Amazon RDS User Guide.

Amazon RDS for PostgreSQL makes it simple to set up, operate, and scale PostgreSQL deployments in the cloud. See Amazon RDS for PostgreSQL Pricing for pricing details and regional availability. Create or update a fully managed Amazon RDS database in the Amazon RDS Management Console.
