CREATE OPERATOR FAMILY(7)          PostgreSQL 14.23 Documentation          CREATE OPERATOR FAMILY(7)



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 38.16 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.
