Hi Greg,

I would vote for the latter so that we could give more meaningful
feedback - for example, when vacuuming you might give a scale of 0 to
<num tables>. In cases such as COPY where you mightn't have any idea of
an upper bound, then a simple heartbeat could be supplied so at least
the client could count rows (or 100's of rows) processed or whatever.

It would certainly allow us to present a nicer user experience in
pgAdmin :-)

Regards, Dave.
