Creating schemas
You can create as many schemas as necessary for your database.
You can create as many schemas as necessary for your database. For example, you could create a schema for each database user. However, schemas and users are not synonymous as they are in Oracle.
By default, only a superuser can create a schema or give a user the right to create a schema. (See GRANT (database) in the SQL Reference Manual.)
To create a schema use the CREATE SCHEMA statement, as described in the SQL Reference Manual.
