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 14.5, 13.8, 12.12, and 11.17 in Amazon Web Services China (Beijing) Region, operated by Sinnet and in Amazon Web Services China (Ningxia) Region, operated by NWCD. 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. As a reminder, if you are running any version of Amazon Aurora PostgreSQL 10, you must upgrade to a newer major version by January 31, 2023.
This release also contains an improvement for logical replication performance. This improvement, enabled as a write-through cache, will help improve the performance of Aurora PostgreSQL when continuously reading a logical replication stream (to minimize replication lag). Each replication slot can read recent data from the cache instead of Aurora Storage. In addition to performance improvements, the cache can help reduce I/O. The cache is available for Aurora PostgreSQL versions 14.5, 13.8, 12.12, and 11.17.
You can initiate a minor version upgrade manually by modifying your DB cluster. Please review the Aurora documentation to learn more.
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 Amazon Web Services services.
