No, you're right.  The only real way to upgrade Postgres today without a
complete dump and restore is some sort of trigger-based replication (like
Slony).  I don't know whether Bucardo or Londiste can do the same trick, but
their design suggests they might be able to.  I also used erserver in the
past to do this, although that was way harder and much scarier.
