Description
  
   DROP SCHEMA removes schemas from the data base.
  
   A schema can only be dropped by its owner or a superuser.  Note that
   the owner can drop the schema (and thereby all contained objects)
   even if he does not own some of the objects within the schema.
  
    Notes
   
    Refer to the CREATE SCHEMA statement for
    information on how to create a schema.
   
   Usage
  
   To remove schema mystuff from the database,
   along with everything it contains:
   
DROP SCHEMA mystuff CASCADE;
