Yes, this is a known problem. Look at
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=225812 and
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=225635
Solution:
If you have an up to date dump, move $PGDATA aside, initdb and load your
dump.
Otherwise:
rm -rf /var/lib/postgres/dumpall/7.3/
reinstall 7.3.4-9 from testing for the packages postgresql,
postgresql-client and libpq3; use dpkg --force-downgrade --force-depends
--force-conflicts to do it - it's only for a few minutes.
Make a dump now
reinstall 7.4.1 - this time the upgrade should work, and if not, you can
do a manual upgrade with your just-taken dump as shown above .
