Scheduled Amazon RDS for PostgreSQL minor version upgrade – System Upgrades CONVOTIS Deutschland Managed Systems

Dear Customer,

We would like to inform you about an upcoming scheduled upgrade for Amazon RDS for PostgreSQL minor version across all environments and regions.

Reason for the upgrade

Starting May 1, 2026, you will not be able to create new database instances on Amazon RDS for PostgreSQL minor versions 14.14, 14.15, 14.16, 14.17, 15.9, 15.10, 15.11, 15.12, 16.5, 16.6, 16.7, 16.8, 17.1, 17.2, 17.3, 17.4, or 11.22-RDS.20241121 from either the AWS Console or the CLI.

During a scheduled maintenance window after May 31, 2026, Amazon RDS will automatically upgrade your Amazon RDS for PostgreSQL databases running minor versions 14.14, 14.15, 14.16, 14.17, 15.9, 15.10, 15.11, 15.12, 16.5, 16.6, 16.7, 16.8, 17.1, 17.2, 17.3, 17.4, or 11.22-RDS.20241121 to version 14.20, 15.15, 16.11, 17.7 (or higher). This also applies to any instances restored from snapshots of these versions.

AWS recommend upgrading these instances to newer minor versions to benefit from patches for known security vulnerabilities, as well as bug fixes, performance improvements, and new functionalities added by the PostgreSQL community.
