User-level schemas
An important use-case for PostgreSQL schemas is the ability to provide database users with their own group of tables that are only accessible to each individual user, such that users' database access does not interfere with others. In the name of security, this can be taken one step further to separate any production tables from being manipulated by unauthorized users. Schemas allow these divisions to be created without the use of multiple databases which can reduce maintenance requirements for database administrators.
