PostgreSQL TPROC-C Benchmarks: PostgreSQL 12

PurposeStarting 26 Apr 2022 , Amazon will start upgrading all Amazon RDS instances using PostgreSQL 9.6 to PostgreSQL 12. Read more about this in their announcement.(This date was originally 18 Jan 2022 but on 17th January, Amazon announced that they were extending the EOL process until 26 Apr 2022 . (This is an additional 14 weeks on the original date)PostgreSQL 12 is not yet supported for Confluence. This means that if your deployment's database is an Amazon RDS instance using PostgreSQL 9.6, you will end up with an unsupported database after 26 Apr 2022.SolutionTo prevent being upgraded to an unsupported database, you'll have to manually upgrade your database instance. We recommend you upgrade to PostgreSQL 10, as this version will differ the least from 9.6. This version is also supported across most versions of Jira, Confluence, Bitbucket Server, and Crowd. Check your database instance's PostgreSQL versionRemember, your database instance will only be automatically upgraded to PostgreSQL 12 if it's using PostgreSQL 9.6 in an Amazon RDS. Otherwise, your database should be safe from the upgrade. Show me how to check my database instance's PostgreSQL version Sign in to the AWS Management Console, use the region selector in the navigation bar to choose the AWS Region for your deployment, and open the AWS RDS console at the navigation pane, click Databases. From there, select your database instance. You can use the search bar to filter instances by name. On your database instance's Summary screen, click the Configuration tab. You can view the Engine version from there.If your Engine version is higher than 9.6, your instance will not be automatically upgraded. If it is 9.6, you'll need to manually upgrade it. tip/resting Created with Sketch. Take a database snapshotBefore you upgrade your database instance's PostgreSQL engine version, we recommend that you take a snapshot of your database.To upgrade your database instance's PostgreSQL engine version from 9.6 to 10:Sign in to the AWS Management Console, use the region selector in the navigation bar to choose the AWS Region for your deployment, and open the AWS RDS console at the navigation pane, click Databases.
