High availability

Configuring high availability to recover from infrastructure failures isn't yet available.


Currently, local monitoring with Grafana is only available for the default postgres database. Metrics dashboards for user created databases will be empty.


System configurations that are stored in are backed up when a base backup is created. This means that changes made after the last base backup, will not be present in a restored server until a new base backup is taken to capture those changes.

Roles and responsibilities

The roles and responsibilities between Microsoft and its customers differ between Azure managed services (Platform As A Service or PaaS) and Azure hybrid (like Azure Arc-enabled PostgreSQL).
