Today, we are announcing that your MySQL 5.7 and PostgreSQL 11 database instances running on Amazon Aurora and Amazon Relational Database Service (Amazon RDS) will be automatically enrolled into Amazon RDS Extended Support starting on February 29, 2024.
This will help avoid unplanned downtime and compatibility issues that can arise with automatically upgrading to a new major version. This provides you with more control over when you want to upgrade the major version of your database.
