The PostgreSQL open-source project regularly issues new releases that can be available to Microsoft Azure cloud customers. By upgrading your Azure PostgreSQL database servers with the new version of PostgreSQL, you will introduce new software features, fix reported bugs through security patches, and provide better compatibility with other applications and services.

Remediation / Resolution
Automated upgrade to a major PostgreSQL engine version is not currently supported. For example, there is not an automatic upgrade from PostgreSQL 9.5 to PostgreSQL version 9.6. To upgrade your Azure PostgreSQL server to the latest major version of the PostgreSQL database, you have to re-create the existing server, export a database dump, and restore it to the PostgreSQL server with the new engine version. To implement the rule remediation process, perform the following actions:
- Azure Official Documentation
- Supported PostgreSQL major versions
- Limits in Azure Database for PostgreSQL - Single Server
- Migrate your PostgreSQL database using dump and restore
