       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

       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 schema-qualified.

              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.
