Failover Between Regions with Azure PostgreSQL Flexible Server without connection string changes

Hi, thanks for the reported note this clearly describes failover phase (the first one) for DR with Azure postgresql flexible server, any news about the second phase of DR , the failback with Azure Postgres ?

As mentioned by harinarayanan94 in the comment above, any other option for the failback procedure (once DR event is resolved, the region is back online and user want to move back to primary region), is really the only chance (yet) to 

"delete the old primary , re-create it and again sync it with the current primary (in DR region) and repoint . and once thats done , again to make our application DR compliant , we have to delete the server in the secondary region and initiate a fresh DR sync with the primary" ?

Besides if the old primary was configured with Backup type "Geo Redundant Backup"  how to reconfigure it from Replica (it seems not allowed), please can you confirm ?
