       CREATE OPERATOR FAMILY - define a new operator family


       CREATE OPERATOR FAMILY name USING index_method


       CREATE  OPERATOR  FAMILY  creates  a  new operator family.  An operator
       family defines a collection of related operator  classes,  and  perhaps
       some  additional  operators  and  support functions that are compatible
       with these operator classes but not essential for  the  functioning  of
       any  individual  index.  (Operators and functions that are essential to
       indexes should be grouped within the relevant  operator  class,  rather
       than  being  ‘‘loose’’ in the operator family.  Typically, single-data-
       type operators are bound to  operator  classes,  while  cross-data-type
       operators  can  be  loose  in  an  operator  family containing operator
       classes for both data types.)

       The new operator family is initially empty. It should be  populated  by
       issuing  subsequent  CREATE  OPERATOR  CLASS  commands to add contained
       operator classes, and optionally ALTER OPERATOR FAMILY commands to  add
       ‘‘loose’’ operators and their corresponding support functions.

       If  a  schema  name is given then the operator family is created in the
       specified schema. Otherwise it is created in the current  schema.   Two
       operator  families  in  the  same schema can have the same name only if
       they are for different index methods.

       The user who defines an operator family becomes its  owner.  Presently,
       the  creating  user  must  be  a  superuser.  (This restriction is made
       because an erroneous operator family definition could confuse  or  even
       crash the server.)

       Refer to in the documentation for further information.


       name   The  name  of the operator family to be created. The name can be

              The name of the index method this operator family is for.


       CREATE OPERATOR FAMILY is a PostgreSQL extension. There  is  no  CREATE
       OPERATOR FAMILY statement in the SQL standard.
