Following the announcement of updates to the PostgreSQL database by the open source community, we have updated Amazon Aurora with PostgreSQL compatibility to support PostgreSQL version 11.8, 10.13 and 9.6.18 in all regions. This release contains bug fixes and improvements by the PostgreSQL community, and improved TLS support from PostgreSQL 12.

Improvements in TLS support that were added in PostgreSQL 12 are now available in the Aurora PostgreSQL 11.8 minor version. This enhancement allows you to configure the minimum SSL/TLS protocol version for secure connections, which is becoming increasingly important as early versions of the TLS protocol (e.g., v1 and v1.1) have known security vulnerabilities. 

You can initiate a minor version upgrade manually by modifying your DB cluster. Or you can enable the* *“Auto minor version upgrade*” *option when creating or modifying a DB cluster. Doing so means that your DB cluster is automatically upgraded after Aurora PostgreSQL tests and approves the new version. For more details, see Automatic Minor Version Upgrades for PostgreSQL. Please review the Aurora documentation to learn more.  

Amazon Aurora combines the performance and availability of high-end commercial databases with the simplicity and cost-effectiveness of open source databases. It provides up to three times better performance than the typical PostgreSQL database, together with increased scalability, durability, and security.
