privateDnsZoneId

The ID of the private DNS zone to create the PostgreSQL Flexible Server. Changing this forces a new PostgreSQL Flexible Server to be created.

NOTE: There will be a breaking change from upstream service at 15th July 2021, the private_dns_zone_id will be required when setting a delegated_subnet_id. For existing flexible servers who don't want to be recreated, you need to provide the private_dns_zone_id to the service team to manually migrate to the specified private DNS zone. The azure.privatedns.Zone should end with suffix .postgres.database.azure.com.
