Amazon RDS for PostgreSQL supports minor versions 17.7, 16.11, 15.15, 14.20, and 13.23

Amazon Relational Database Service (RDS) for PostgreSQL now supports the latest minor versions 17.7, 16.11, 15.15, 14.20, and 13.23. We recommend that you upgrade to the latest minor versions to fix known security vulnerabilities in prior versions of PostgreSQL, and to benefit from the bug fixes added by the PostgreSQL community.

This release includes the new pgcollection extension for RDS PostgreSQL versions 15.15 and above (16.11 and 17.7). This extension enhances database performance by providing an efficient way to store and manage key-value pairs within PostgreSQL functions. Collections maintain the order of entries and can store various types of PostgreSQL data, making them useful for applications that need fast, in-memory data processing.
The release also includes updates to extensions, with pg_tle upgraded to version 1.5.2 and H3_PG upgraded to version 4.2.3.

You can use automatic minor version upgrades to automatically upgrade your databases to more recent minor versions during scheduled maintenance windows. You can also use Amazon RDS Blue/Green deployments for RDS for PostgreSQL using physical replication for your minor version upgrades. Learn more about upgrading your database instances, including automatic minor version upgrades and Blue/Green deployments in the Amazon RDS User Guide .
