NAME
       ALTER OPERATOR - change 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 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.

       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 ALTER OPERATOR statement in the SQL standard.
