PostgreSQL 11 includes major improvements to partitioning and parallelism, and many useful performance improvements like adding columns with a non-null column default faster. It supports SQL stored procedures that allow embedded transactions within a procedure.
To upgrade, select the "Modify" option on the AWS Management Console corresponding to the DB instance you want to upgrade, choose the version of Aurora PostgreSQL 11 you want to upgrade to, and proceed with the wizard. Some of the earlier versions may not be available for upgrade to avoid the possibility of upgrading to a version that was released by the community before your current version. The upgrade will be applied immediately (if you select the "Apply Immediately" option), or during your next maintenance window (by default). Note that in either case, you database will be unavailable for a few minutes as the upgrade completes and your database instances are rebooted. Please review the Aurora documentation to learn more.
The feature is available in all regions supported by Aurora Aurora with PostgreSQL compatibility.
