   Description
  
   DROP USER removes the specified user from the database.
   It does not remove tables, views, or other objects owned by the user. If the
   user owns any database you get an error.
  
   Use CREATE USER
   to add new users, and ALTER USER to change a user's properties.
   PostgreSQL
   comes with a script dropuser
   which has the same functionality as this command (in fact, it calls this command)
   but can be run from the command shell.
  
   Usage
  
   To drop a user account:
DROP USER jonathan;
