Synopsis

Use the CREATE OPERATOR CLASS statement to create an operator class.

Syntax

create_operator_class ::= CREATE OPERATOR CLASS operator_class_name 
                          [ DEFAULT ] FOR TYPE data_type USING 
                          index_method AS operator_class_as [ , ... ]

operator_class_as ::= OPERATOR strategy_number operator_name 
                      [ ( operator_signature ) ] [ FOR SEARCH ]
                      | FUNCTION support_number 
                        [ ( op_type [ , ... ] ) ] subprogram_name ( 
                        subprogram_signature )
                      | STORAGE storage_type

Semantics

See the semantics of each option in the [PostgreSQL docs][postgresql-docs-create-op-class]. See the semantics of strategy_number and support_number in another page of the [PostgreSQL docs][postgresql-docs-xindex].

Examples

Basic example.

yugabyte=# CREATE OPERATOR CLASS my_op_class
           FOR TYPE int4
           USING btree AS
           OPERATOR 1 <,
           OPERATOR 2 <=;
