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



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 CAS-
       CADE 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.
