Database Users and Privileges
Database users should only have access to the database resources that they need to perform their tasks. For example, most users should be able to read data but not modify or insert new data. A smaller number of users typically need permission to perform a wider range of database tasks—for example, create and modify schemas, tables, and views. A very small number of can perform administrative tasks, such as rebalance nodes on a cluster, or start or stop a database. You can also let certain users extend their own privileges to other users.
Client authentication controls what database objects users can access and change in the database. You specify access for specific users or roles with GRANT statements.
