PostgreSQL Minor Version upgrade now available in EU-DE and EU-NL

Precautions:

  •  You are advised to perform a full backup before upgrading a minor version.
  • When any new minor version is released to address vulnerabilities and other issues from the opensource community, perform a minor version upgrade for your instance.
  • The upgrade will cause the instance to reboot and interrupt services for a short 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 need to re-establish a Disaster Recovery (DR) relationship after upgrading the minor version of a DR instance.
  • Before upgrading minor versions earlier than RDS for PostgreSQL 12.6, you need to stop all logical replications and delete all logical replication slots. Otherwise, the upgrade will fail.
    • Querying a replication slot: select * from pg_replication_slots;
    • Deleting a replication slot: select pg_drop_replication_slot('SLOT_NAME');

 
Constraints:

  • The minor version cannot be upgraded for instances with abnormal nodes.
  • The following minor version cannot be upgraded:
    • Versions earlier than 11.2 for RDS for PostgreSQL 11
  • The upgrade will be performed immediately upon the submission of your request. Delayed upgrade of minor versions is not supported.
