NAME

       CREATE OPERATOR FAMILY - define a new operator family

SYNOPSIS

       CREATE OPERATOR FAMILY name USING index_method

DESCRIPTION

       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.

PARAMETERS

       name   The name of the operator family to be created. The name can be schema-qualified.

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

COMPATIBILITY

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