Amazon Aurora Serverless v1 now supports PostgreSQL major version 13. PostgreSQL 13 includes improved functionality and performance from enhancements such as de-duplication of B-tree index entries, improved performance for queries that use partitioned tables, incremental sorting to accelerate data sorts, parallel processing of indexes with the VACUUM command, more ways to monitor activity within a PostgreSQL database, new security capabilities, and more.
Aurora Serverless v1 also supports in-place upgrade from PostgreSQL 11 to 13. Instead of backing up and restoring the database to the new version, you can upgrade with just a few clicks in the AWS Management Console or using the latest AWS SDK or CLI. No new cluster is created in the process which means you keep the same endpoints and other characteristics of the cluster. The upgrade completes in minutes and can be applied immediately or during the maintenance window. Your database cluster will be unavailable during the upgrade.
