Automatically? Well, you can install the two versions side-by-side, and do
pg_upgradecluster, which ports your configuration to the new version and does
a pg_dump between the two versions; exactly what a system administrator would

great deal of the not-so-simple cases. I did this for our cluster the other
day (130 wildly different databases, from 7.4 to 8.1) and it worked
flawlessly.
I do not really see why all the distributions could do something like this,
instead of mucking around with special statically compiled pg_dumps and the
