CLASS(7) 				  PostgreSQL 9.2.7 Documentation				   ALTER OPERATOR CLASS(7)

NAME

       ALTER_OPERATOR_CLASS - change the definition of an operator class

SYNOPSIS

       ALTER OPERATOR CLASS name USING index_method RENAME TO new_name
       ALTER OPERATOR CLASS name USING index_method OWNER TO new_owner
       ALTER OPERATOR CLASS name USING index_method SET SCHEMA new_schema

DESCRIPTION

       ALTER OPERATOR CLASS changes the definition of an operator class.

       You must own the operator class to use ALTER OPERATOR CLASS. To alter the owner, you must also be a direct or indirect member of the new
       owning role, and that role must have CREATE privilege on the operator class's schema. (These restrictions enforce that altering the owner
       doesn't do anything you couldn't do by dropping and recreating the operator class. However, a superuser can alter ownership of any operator
       class anyway.)

PARAMETERS

       name
	   The name (optionally schema-qualified) of an existing operator class.

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

       new_name
	   The new name of the operator class.

       new_owner
	   The new owner of the operator class.

       new_schema
	   The new schema for the operator class.

COMPATIBILITY

       There is no ALTER OPERATOR CLASS statement in the SQL standard.

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.
