ALTER OPERATOR

ALTER OPERATOR

Changes the definition of an operator.

Synopsis

ALTER OPERATOR name ( {lefttype | NONE} , {righttype | NONE} ) 
   OWNER TO newowner

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 use ALTER OPERATOR. 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's schema. (These restrictions enforce that altering the owner does not do anything you could not 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.
lefttype
The data type of the operator's left operand; write NONE if the operator has no left operand.
righttype
The data type of the operator's right operand; write NONE if the operator has no right operand.
newowner
The new owner of the operator.

Examples

Change the owner of a custom operator a @@ b for type text:

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

Compatibility

There is no ALTEROPERATOR statement in the SQL standard.
