CREATE OP...OR FAMILY(7) PostgreSQL 18.6 Documentation CREATE OP...OR 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 addi- tional operators and support functions that are compatible with these oper- ator 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 opera- tor 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 issu- ing subsequent CREATE OPERATOR CLASS commands to add contained operator classes, and optionally ALTER OPERATOR FAMILY commands to add "loose" oper- ators and their corresponding support functions. If a schema name is given then the operator family is created in the speci- fied 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 er- roneous operator family definition could confuse or even crash the server.) Refer to Section 36.16 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 OPERA- TOR FAMILY statement in the SQL standard.
