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

NAME

       DROP OPERATOR FAMILY - remove an operator family

SYNOPSIS

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

DESCRIPTION

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

       DROP OPERATOR FAMILY includes dropping any operator classes contained in the family, but it does not drop any of the operators or functions
       referenced by the family. If there are any indexes depending on operator classes within the family, you will need to  specify  CASCADE  for
       the drop to complete.

PARAMETERS

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

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

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

       CASCADE
	      Automatically drop objects that depend on the operator family.

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

EXAMPLES

       Remove the B-tree operator family float_ops:

       DROP OPERATOR FAMILY float_ops USING btree;

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

COMPATIBILITY

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