Tell HN: Critical issue in Aurora PostgreSQL Serverless v2

4 points

4 years ago

We have identified a critical stability update for Aurora PostgreSQL Serverless v2 instances running versions 13.6, 13.7, and 14.3. We have also identified a critical issue in Aurora PostgreSQL Serverless v2 clusters running versions 13.7 and 14.3. These issues can cause database restarts or failovers under specific conditions. We have developed fixes and are deploying the fixes in two patches. The patches will be automatically applied to the affected instances and clusters in upcoming maintenance windows over the next 3 weeks causing two restarts of your database. One patch will show as a security and stability update and one patch will show as a database update. They will be scheduled sequentially.

How to Determine Which Instances are Running These Versions?

- In the Amazon RDS console, you can see details about a database cluster, including the Aurora PostgreSQL version of instances in the cluster, by choosing Databases from the console’s navigation pane.

- To view DB cluster information by using the AWS CLI, use the describe-db-clusters command.

- To view DB cluster information using the Amazon RDS API, use the DescribeDBClusters operation. You can also query a database directly to get the version number by querying the aurora_version() system function i.e., “SELECT * FROM aurora_version();“.
