PostgreSQL 11 support in Single Server and Flexible Server

Azure is extending support for PostgreSQL 11 in Single Server and Flexible Server by one more year until November 9, 2024.

  • You will be able to create and use your PostgreSQL 11 servers until November 9, 2024 without any restrictions. This extended support is provided to help you with more time to plan and migrate to Flexible server for higher PostgreSQL versions.
  • Until November 9, 2023, Azure will continue to update your PostgreSQL 11 server with PostgreSQL community provided minor versions.
  • Between November 9, 2023 and November 9, 2024, you can continue to use your PostgreSQL 11 servers and create new PostgreSQL servers without any restrictions. However, other retired PostgreSQL engine restrictions apply.
  • Beyond Nov 9 2024, all retired PostgreSQL engine restrictions apply.

Retired PostgreSQL engine versions not supported in Azure Database for PostgreSQL

You may continue to run the retired version in Azure Database for PostgreSQL. However, note the following restrictions after the retirement date for each PostgreSQL database version:

  • As the community will not be releasing any further bug fixes or security fixes, Azure Database for PostgreSQL will not patch the retired database engine for any bugs or security issues, or otherwise take security measures with regard to the retired database engine. You may experience security vulnerabilities or other issues as a result. However, Azure will continue to perform periodic maintenance and patching for the host, OS, containers, and any other service-related components.
  • If any support issue you may experience relates to the PostgreSQL engine itself, as the community no longer provides the patches, we may not be able to provide you with support. In such cases, you will have to upgrade your database to one of the supported versions.
  • You will not be able to create new database servers for the retired version. However, you will be able to perform point-in-time recoveries and create read replicas for your existing servers.
  • New service capabilities developed by Azure Database for PostgreSQL may only be available to supported database server versions.
  • Uptime SLAs will apply solely to Azure Database for PostgreSQL service-related issues and not to any downtime caused by database engine-related bugs.
  • In the extreme event of a serious threat to the service caused by the PostgreSQL database engine vulnerability identified in the retired database version, Azure may choose to stop your database server to secure the service. In such case, you will be notified to upgrade the server before bringing the server online.

PostgreSQL version syntax

Before PostgreSQL version 10, the PostgreSQL versioning policy considered a major version upgrade to be an increase in the first or second number. For example, 9.5 to 9.6 was considered a major version upgrade. As of version 10, only a change in the first number is considered a major version upgrade. For example, 10.0 to 10.1 is a minor release upgrade. Version 10 to 11 is a major version upgrade.
