What is the difference between a database user and a schema?
You can consider that a user is the account you use to connect to a database, and a schema is the set of objects (tables, views, etc.) that belong to that account.
How to create a schema for a PostgreSQL database?
To create a schema, the invoking user must have the CREATE privilege for the current database. (Of course, superusers bypass this check.) Create a schema for user joe; the schema will also be named joe: Create a schema named test that will be owned by user joe, unless there already is a schema named test.
Do you have create and usage privileges on a schema?
To allow that, the CREATE privilege on the schema needs to be granted. Note that by default, everyone has CREATE and USAGE privileges on the schema public. This allows all users that are able to connect to a given database to create objects in its public schema. If you do not want to allow that, you can revoke that privilege:
Can a user create an object in another schema?
To allow that, the owner of the schema needs to grant the USAGE privilege on the schema. To allow users to make use of the objects in the schema, additional privileges may need to be granted, as appropriate for the object. A user can also be allowed to create objects in someone else’s schema.
Can a schema name begin with PG _?
The name cannot begin with pg_, as such names are reserved for system schemas. The role name of the user who will own the new schema. If omitted, defaults to the user executing the command. To create a schema owned by another role, you must be a direct or indirect member of that role, or be a superuser.
