APPLIES TO: Azure Database for PostgreSQL - Single Server

This article describes how you can configure an Azure Database for PostgreSQL server storage to grow without impacting the workload.

When a server reaches the allocated storage limit, the server is marked as read-only. However, if you enable storage auto grow, the server storage increases to accommodate the growing data. For servers with less than 100 GB provisioned storage, the provisioned storage size is increased by 5 GB as soon as the free storage is below the greater of 1 GB or 10% of the provisioned storage. For servers with more than 100 GB of provisioned storage, the provisioned storage size is increased by 5% when the free storage space is below 10GB of the provisioned storage size. Maximum storage limits as specified here apply.
