   Description
  
   DROP SEQUENCE removes sequence number generators from the
   data base. With the current implementation of sequences as
   special tables it works just like the DROP TABLE
   statement.
  
    Notes
   
    The DROP SEQUENCE statement is a
    PostgreSQL
    language extension.
   
    Refer to the CREATE SEQUENCE statement for
    information on how to create a sequence.
   
   Usage
