docs: Restore the `dump` database into the new `db` database.
          The `dump` file object can be obtained with the
          :func:`dump <DB.dump>` method.
          If `copy` is set to `True`, the restored database will have a new UUID.
  
          >>> odoo.db.restore('super_admin_passwd', 'test', dump_file) # doctest: +SKIP
  
          If you get a timeout error, increase this one before performing the
          request:
  
          >>> timeout_backup = odoo.config['timeout']
          >>> odoo.config['timeout'] = 7200   # Timeout set to 2 hours
          >>> odoo.db.restore('super_admin_passwd', 'test', dump_file) # doctest: +SKIP
          >>> odoo.config['timeout'] = timeout_backup
  
          The super administrator password is required to perform this method.
