Public preview: Read replicas in Azure Database for PostgreSQL
Published date: January 21, 2019
You can now replicate data from a single Azure Database for PostgreSQL server (master) to up to five read-only servers (read replicas) within the same Azure region. This feature uses PostgreSQL's native asynchronous replication.
With read replicas, you can scale out your read-intensive workloads. Read replicas can also be used for BI and reporting scenarios. You can choose to stop replication to a replica, in which case it becomes a normal read/write server.
