Upgrading a Minor Version

Scenarios

RDS for PostgreSQL supports minor version upgrades to improve performance, add new functions, and fix bugs.

Precautions

  • When any new minor version is released to address vulnerabilities and other issues from the open source community, perform a minor version upgrade for your instance.
  • The upgrade will cause the instance to reboot and interrupt services for a period of time. The length of the interruption depends on service volume. To minimize the impact of the upgrade, perform the upgrade during off-peak hours, or ensure that your applications support automatic reconnection.
  • When you upgrade the minor version of a primary instance, the minor versions of read replicas (if any) will also be upgraded automatically. Read replicas cannot be upgraded separately.
  • A minor version upgrade cannot be rolled back after the upgrade is complete. If the upgrade fails, the DB instance will be automatically rolled back to the source version.
  • You are advised to perform a full backup before upgrading a minor version.
  • You need to re-establish a DR relationship after upgrading the minor version of a DR instance.

Constraints

  • The minor version cannot be upgraded for instances with abnormal nodes.
  • The upgrade will be performed immediately upon the submission of your request. Delayed upgrade of minor versions is not supported.

Procedure

  1. Log in to the management console.
  2. Click in the upper left corner and select a region and a project.
  3. Click Service List. Under Database, click Relational Database Service. The RDS console is displayed.
  4. On the Instances page, click the primary instance name to go to the Overview page.
  5. Under DB Engine Version, click Upgrade Minor Version.
  6. In the displayed dialog box, click OK.

    RDS upgrades the minor version to the latest version immediately.
