NAME

       DROP OPERATOR CLASS - remove an operator class

SYNOPSIS

       DROP OPERATOR CLASS [ IF EXISTS ] name USING index_method [ CASCADE | RESTRICT ]

DESCRIPTION

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

       DROP OPERATOR CLASS does not drop any of  the  operators  or  functions
       referenced  by  the  class.  If  there are any indexes depending on the
       operator class, you will need  to  specify  CASCADE  for  the  drop  to
       complete.

PARAMETERS

       IF EXISTS
              Do  not  throw  an error if the operator class does not exist. A
              notice is issued in this case.

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

       index_method
              The name of the index access method the operator class is for.

       CASCADE
              Automatically drop objects that depend on the operator class.

       RESTRICT
              Refuse  to  drop the operator class if any objects depend on it.
              This is the default.

NOTES

       DROP OPERATOR CLASS will not drop the operator  family  containing  the
       class, even if there is nothing else left in the family (in particular,
       in the case where the family was implicitly created by CREATE  OPERATOR
       CLASS).  An  empty  operator  family  is  harmless, but for the sake of
       tidiness you might wish to remove the family with DROP OPERATOR FAMILY;
       or perhaps better, use DROP OPERATOR FAMILY in the first place.

EXAMPLES

       Remove the B-tree operator class widget_ops:

       DROP OPERATOR CLASS widget_ops USING btree;

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

COMPATIBILITY

       There is no DROP OPERATOR CLASS statement in the SQL standard.
