Ensure backup retention period is enabled for Azure PostgreSQL…

Enabling automatic backups can help prevent data loss for a PostgreSQL server. Azure can create and save backups in either locally redundant or geo-redundant storage for greater resiliency, with geo-redundant storage providing the greatest availability. The maximum retention period for PostgreSQL backup storage is 35 days and they are encrypted by default. For more information, see the Azure documentation.
