Hi,

In Oracle, there are 2 ways to do the equivalent of vacuum analyze :

* analyze table xx compute statitics
* analyze table xx estimate statistics

In the second form, you can tell on what percentage of the file you
will do your stats. This is useful to make a quick analyze on huge tables
that have a homogenous dispersion.

Is there a way to "estimate" the statistics that vacuum analyze will
use instead of "computing" them ?
