[Announcement]: Urgent Action Required - Upgrade your RDS for PostgreSQL minor versions

1

This announcement is for customers that are running one or more Amazon RDS DB instances with a version of PostgreSQL, that has been deprecated by Amazon RDS and requires attention.

The RDS PostgreSQL minor versions that are listed in the table below are supported, and any DB instances running earlier versions will be automatically upgraded to the version marked as "preferred" by RDS, no earlier than July 15, 2022 starting 12 AM PDT:

Major Versions SupportedMinor Versions Supported
1414.1 and later
1313.3 and later
1212.7 and later
1111.12 and later
1010.17 and later

Amazon RDS supports DB instances running the PostgreSQL minor versions listed above. Minor versions not included above do not meet our high quality, performance, and security bar. In the PostgreSQL versioning policy [1] the PostgreSQL community recommends that you always run the latest available minor release for whatever major version is in use. Additionally, we recommend that you monitor the PostgreSQL security page for documented vulnerabilities [2].

If you have automatic minor version upgrade enabled as a part of your configuration settings, you will be automatically upgraded. Alternatively, you can take action yourselves by performing the upgrade earlier. You can initiate an upgrade by going to the Modify DB Instance page in the AWS Management Console and change the database version setting to a newer minor/major version of PostgreSQL. Alternatively, you can also use the AWS CLI to perform the upgrade. To learn more about upgrading PostgreSQL minor versions in RDS, review the 'Upgrading Database Versions' page [3].

The upgrade process will shutdown the database instance, perform the upgrade, and restart the database instance. The DB instance may restart multiple times during the process. If you choose the "Apply Immediately" option, the upgrade will be initiated immediately after clicking on the "Modify DB Instance" button. If you choose not to apply the change immediately, the upgrade will be performed during your next maintenance window.

Starting no earlier than July 15, 2022 12 AM PDT, we will automatically upgrade the DB instances running deprecated minor version to the preferred minor version of the specific major version of your RDS PostgreSQL database. (For example, instances running RDS PostgreSQL 10.1 will be automatically upgraded to 10.17 starting no earlier than July 15, 2022 12 AM PDT)

Should you need to create new instances using the deprecated version(s) of the database, we recommend that you restore from a recent DB snapshot [4]. You can continue to run and modify existing instances/clusters using these versions until July 14, 2022 11:59 PM PDT, after which your DB instance will automatically be upgraded to the preferred minor version of the specific major version of your RDS PostgreSQL database.

Starting no earlier than July 15, 2022 12 AM PDT, restoring the snapshot of a deprecated RDS PostgreSQL database instance will result in an automatic version upgrade of the restored database instance using the same upgrade process as described above.

Should you have any questions or concerns, please see the RDS FAQs [5] or you can contact the AWS Support Team on the community forums and via AWS Support [6].

Sincerely,

Amazon RDS
