Following the announcement of updates to the PostgreSQL database by the open source community, we have updated Amazon Aurora PostgreSQL-Compatible Edition to support PostgreSQL 13.7, 12.11, 11.16, and 10.21. These releases contain bug fixes and improvements by the PostgreSQL community. Refer to the Aurora version policy to help you to decide how often to upgrade and how to plan your upgrade process.

This release also includes updates to pglogical and wal2json extensions. pglogical is an open source PostgreSQL extension that helps customers replicate data between independent PostgreSQL databases while maintaining consistent read-write access and a mix of private and common data in each database. Amazon Aurora pglogical uses logical replication to copy data changes between independent PostgreSQL databases, optionally resolving conflicts based on standard algorithms. Customers can enable pglogical from within their PostgreSQL instances, and pay only for the additional clusters and cross-region traffic needed, with no upfront costs or software purchases required. Fully integrated, pglogical requires no triggers or external programs. This alternative to physical replication is a highly efficient method of replicating data using a publish/subscribe model for selective replication.

wal2json is an output plugin for logical decoding. Logical decoding is the process of extracting all persistent changes to a database’s tables into a coherent, easy to understand format which can be interpreted without detailed knowledge of the database’s internal state. Customers can use the extension to export the output of the PostgreSQL write-ahead log (WAL) into JSON objects.

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. By doing so, your DB cluster is automatically upgraded after AWS tests and approves the new version. For more details, see Automatic Minor Version Upgrades for PostgreSQL. Please review the Aurora documentation to learn more. For full feature parity list, head to our feature parity page, and to see all the regions that support Amazon Aurora head to our region page.

Amazon Aurora is designed for unparalleled high performance and availability at global scale with full MySQL and PostgreSQL compatibility. It provides built-in security, continuous backups, serverless compute, up to 15 read replicas, automated multi-Region replication, and integrations with other AWS services.
