Amazon Aurora PostgreSQL-Compatible Edition has added support for PostgreSQL versions 18.4, 17.10, 16.14, 15.18, and 14.23, incorporating bug fixes from the PostgreSQL community and Aurora-specific enhancements. AWS recommends upgrading to these latest minor versions to address known CVEs and leverage improvements detailed in the release notes. The upgrades can be performed during scheduled maintenance windows using automatic minor version upgrades.

To streamline operations at scale, AWS advises enabling automatic minor version upgrades and utilizing the AWS Organizations Upgrade Rollout Policy. This policy allows phased orchestration of multiple upgrades, enabling validation on lower-priority environments before addressing critical systems. The process ensures systematic and controlled updates across large database deployments.
