Hi Winking ,
Unfortunately, not all Azure services support cross-region moves, and Azure Database for PostgreSQL flexible server is one of them. To consolidate your resources in one location, you'll need to create a new PostgreSQL flexible server in your desired region. Then, migrate your data and configurations from the existing server to the new one. Utilize Azure Database migration tools and scripts for a smooth transition. Remember to update your application connection strings to point to the new server location. While this may involve some downtime during migration, it's currently the most viable option for achieving your goal within Azure's constraints. Regards, Saravanan Ganesan.
