Database User
When you create a virtual database server, create the database management user and the system user as well.
Database Management User (Master User)
When you create the virtual database server, create the master user, who connects to the database and manages the database. The following privileges are granted to the master user:
- create role
- create db
- login
Warning: When changing the password for the database management user, use the API for changing database virtual servers. If the database management user is deleted or modified without using the API, there will be serious effects on operation. Do not perform deletion or modification.
System User
When you create a virtual database server, a system user (cloud-user) is created to enable operation from the system. The following privileges are granted to the system user:
- superuser
- create role
- create db
- replication
The system user cannot be used to connect to databases of the virtual database server from a DB client.
Warning: If the system user is deleted or modified, there will be serious effects on operation. Do not perform deletion or modification.
