DROP OPERATOR FAMILY(7)		 SQL Commands	       DROP OPERATOR FAMILY(7)

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	opera‐
       tor 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.
