Well, I figured this out, but I was quite surprised. "Hmmm, where in
hell did configure catch 8.1? dpkg -l \*8.1\* -> nothing."

Compiling server-side extensions, e.g. Slony, might be critical to allow
an upgrade of the DB server at all.
(Slony is one of the solutions that allows to migrate huge databases, by
setting up a cluster with different versions of postgresql, switching
master node, and you've upgraded, with perhaps 30s all in all downtime
to your application. Dumping and reloading the database in our case
would have taken at least 30mins, which would have been accepted in this
case by management, but our db is currently small after 1 month or so of
operation.)
