Amazon RDS for PostgreSQL

Amazon RDS for PostgreSQL now supports the latest minor versions 18.3, 17.9, 16.13, 15.17, and 14.22. These versions address the regression from the February 12, 2026 PostgreSQL community release. We recommend upgrading to the latest minor versions to fix known security vulnerabilities and benefit from bug fixes.

Upgrade your databases during scheduled maintenance windows using automatic minor version upgrades. To simplify operations at scale, enable automatic minor version upgrades and use the AWS Organizations Upgrade Rollout Policy to orchestrate upgrades in phases. You can also use Amazon RDS Blue/Green deployments with physical replication to minimize downtime for minor version upgrades.

What to do

  • Enable automatic minor version upgrades.
  • Use AWS Organizations Upgrade Rollout Policy for phased upgrades.
  • Consider Amazon RDS Blue/Green deployments for minimal downtime.
