The example given has "Seq Scan on tenk1 (cost=0.00..458.00" in the example,
but then says, "you will find out that tenk1 has 358 disk pages" and "the
cost is estimated at 358 page reads".  Shouldn't this be 458 disk page

I couldn't see this already discussed on this list.  Is there a URL that has
the latest docs compiled from CVS?
