It probably means:
create view myview (name, salary, hours) as select lname, currsal, whours from wages;

    But that doesn't have to do anything with the rewrite system.
    It has to do with the view creation step on  setting  up  the
    instead rule for view selection. There the AS clauses have to
    be moved into the target list.  The  rewrite  system  doesn't
    know if this rule is something that builds up a view.
