Imho it is not a good idea at all. The statistics are a very sensitive area,
that imho should only be calculated on request. I already don't like the
statistics that are implicitly created during create index.
Eighter you have online stats keeping or you don't.
For me this is a definite all or nothing issue. Anything inbetween is
only good for unpleasant surprises.
I have very strong feelings about this, because of bad experience.
I would be willing to go into detail.
A syntactic extension to copy ("with analyze") on the other hand would
be a feature.
