To manage a database, you can either use an existing instance or add a new instance.
From the navigation pane, go to Protect > Databases.
The Instances page appears.
Click Add instance, and then select Cloud DB.
The Add Cloud DB instance dialog box appears.
From the Select vendor list, select a vendor where you want to create an instance.
From the Database service list, select PostgreSQL.
From the Cloud account list, select a hypervisor.
If you do not have a hypervisor to select, you can add a hypervisor. For more information, see Adding a Hypervisor.
From the Backup plan list, select a server plan.
From the Instance name list, select an instance.
In the Database user box, type the user name to access the ApsaraDB RDS for PostgreSQL application.
In the Password box, type the password to access the ApsaraDB RDS for PostgreSQL application.
In the Maintenance DB box, type the name of the system database that is used as the maintenance database.
The new instance contains a dump-based backup set and a default subclient.
When you add an instance, a default database group is automatically created. The default database group includes all the data in the PostgreSQL database. You cannot delete the default database group.
