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 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 CRE-
       ATE 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 opera-
       tor.  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.

SEE ALSO
       CREATE OPERATOR [create_operator(7)], DROP OPERATOR [drop_operator(l)]
