ALTER OPERATOR()		 SQL Commands		      ALTER OPERATOR()



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 cur-
       rently 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.
