<p dir="ltr">I agree that it seems inappropriate to preserve order.  That seems an inappropriate imposition,
inconsistentwith what SQL does elsewhere.<p dir="ltr"> If there is a natural sequence (e.g. - a value assigned by
nextval()),that offers a natural place to apply the usual order-imposing ORDER BY that we are expected to use
elsewhere.<pdir="ltr"> I suppose it is troublesome if there is no such natural sequence, but I wouldn't think it too
meaningfulto expect order without some visible source of order.
