ALTER OPERATOR

Name

ALTER OPERATOR -- change the definition of an operator

Synopsis

ALTER OPERATORname ( {left_type | NONE } , {right_type | NONE } ) OWNER TOnew_ownerALTER OPERATORname ( {left_type | NONE } , {right_type | NONE } ) SET SCHEMAnew_schema

Description

ALTER OPERATOR changes the definition of an operator. The only currently available functionality is to change the owner of the operator.

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

Parameters

name: The name (optionally schema-qualified) of an existing operator.
left_type: The data type of the operator's left operand; writeNONE if the operator has no left operand.
right_type: The data type of the operator's right operand; writeNONE if the operator has no right operand.
new_owner: The new owner of the operator.
new_schema: The new schema for the operator.

Examples

Change the owner of a custom operatora @@ b for typetext:

ALTER OPERATOR @@ (text, text) OWNER TO joe;

Compatibility

There is noALTER OPERATOR statement in the SQL standard.
