AWSでPostgreSQLを前から使っている方はアップグレードメンテナンスが必要です
AWSのサポートからこんなメールが届きました。 Dear Amazon RDS Customer, A system update is now available for any Amazon RDS PostgreSQL database instances you created before 13 October 2015. We recommend installing this update to take advantage of several performance improvements and security fixes. You may choose to install this update immediately, or during your next scheduled maintenance window. After approximately six weeks, your RDS instance will be automatically upgraded during your maintenance window. To learn more about scheduling or installing an upgrade, please refer to the RDS documentation: http://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/USER_UpgradeDBInstance.OSUpgrades.html. Installing this update will have an availability impact for a few minutes on your RDS instance (60-120 seconds for Multi-AZ instances). To reduce downtime, you may consider converting your Single-AZ instances to Multi-AZ. If you have any questions or concerns, please contact your TAM or AWS Support. Sincerely, The
