Announcement on the discontinuation of some minor engine versions - ApsaraDB RDS

Some minor engine versions for ApsaraDB RDS for PostgreSQL have security risks. Starting December 13, 2023, the minor engine versions are discontinued. If your RDS instance runs one of the minor engine versions, we recommend that you update the minor engine version at the earliest opportunity.

Involved instances

If your ApsaraDB RDS for PostgreSQL instance meets one of the following conditions, the minor engine version of the RDS instance has risks.

The RDS instance runs PostgreSQL 11 or later and a minor engine version of 20230630 or 20230830.
The RDS instance for which Babelfish is enabled runs PostgreSQL 13 or PostgreSQL 14 and any minor engine version.

Note

You can use one of the following methods to check whether an RDS instance meets the conditions:

Go to the Basic Information page of the RDS instance to view the major engine version and minor engine version.
Use SQL statements:
- Execute the SELECT version(); statement to view the major engine version of an RDS instance.
- Execute the SHOW rds_release_date; statement to view the minor engine version of an RDS instance.

Update methods and recommended versions

Original instance	Destination instance version	Update method
Regular RDS instance	20231030 or later	Update the minor engine version of the original RDS instance. For more information, see Update the minor engine version.

Impacts

Involved instance	Impact
Regular RDS instance	If this is the first time that you purchase an RDS instance, you cannot specify 20230630 or 20230830 for the minor engine version on the ApsaraDB RDS buy page. If your RDS instance does not run a minor engine version of 20230630 or 20230830, you cannot select 20230630 or 20230830 when you update the minor engine version of your RDS instance. If your RDS instance runs a minor engine version of 20230630 or 20230830, the system does not force the update of the minor engine version. If you continue to use the minor engine version, security risks may occur. We recommend that you update the minor engine version to 20231030 or later at the earliest opportunity.
RDS instance with Babelfish enabled	If this is the first time that you purchase an RDS instance with Babelfish enabled, you can select only PostgreSQL 15 on the ApsaraDB RDS buy page. You cannot select PostgreSQL 13 or PostgreSQL 14. If you are using an RDS instance that runs PostgreSQL 13 or PostgreSQL 14 with Babelfish enabled, the system does not force the update of the minor engine version. If you continue to use the minor engine version, security risks may occur. We recommend that you use DTS to migrate data from your RDS instance to an RDS instance that runs PostgreSQL 15 with Babelfish enabled. For more information, see What is DTS? If you are using an RDS instance that runs PostgreSQL 15 with Babelfish enabled, your RDS instance is not affected.
