Log message:
    In UpdateStats(), don't bother to update the pg_class row if it already
    contains the correct statistics.  This is a partial solution for the
    problem of allowing concurrent CREATE INDEX commands: unless they commit
    at nearly the same instant, the second one will see the first one's
    pg_class updates as committed, and won't try to update again, thus
    avoiding the 'tuple concurrently updated' failure.
