Right, but I think Bruce's point is that it is far too easy to get those
things wrong; especially point 2 for which a straight tar dump will
simply not contain the information you need to determine what is a safe
stopping point.
I agree with Bruce that we should have some mechanism that doesn't rely
on the DBA to get this right. Exactly what the mechanism should be is
certainly open for discussion...
