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 Section 35.14, “Interfacing Extensions To Indexes”, 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.
