NAME
       DROP OPERATOR CLASS - remove a user-defined operator class

SYNOPSIS
       DROP OPERATOR CLASS name USING access_method [ CASCADE | RESTRICT ]

   INPUTS
       name   The name (optionally schema-qualified) of an existing operator class.

       access_method

DESCRIPTION
       DROP OPERATOR CLASS drops an existing operator class from the database.	To  execute  this
       command you must be the owner of the operator class.

   NOTES
       The DROP OPERATOR CLASS statement is a PostgreSQL language extension.

       Refer to CREATE OPERATOR CLASS [create_operator_class(7)] for information on how to create
       operator classes.

USAGE
       Remove B-tree operator class widget_ops:

       DROP OPERATOR CLASS widget_ops USING btree;

       This command will not execute if there are any existing	indexes  that  use  the  operator
       class. Add CASCADE to drop such indexes along with the operator class.

COMPATIBILITY
   SQL92
       There is no DROP OPERATOR CLASS in SQL92.
