AZ467519 - Public Preview: Managed Service Identity for Azure Storage extension in Azure Database for PostgreSQL

You can now use Managed Service Identity to authenticate the Azure Storage extension in Azure Database for PostgreSQL – Flexible Server against Azure Blob Storage accounts. The Azure Storage extension enables interactions with Azure Blob Storage accounts from within Azure Database for PostgreSQL - Flexible Server. The extension supports both reading from and writing to Azure Blob Storage accounts, including the built-in COPY command of PostgreSQL. 

With this change, you no longer need to store access keys and shared access signature (SAS) tokens within your database.
