Lost access after upgrading from pg_8.1 to 8.3 on (Debian/Lenny) powerpc

Hi all!

I had a working postgresql_8.1 version but having switched to
'Debian/Lenny (testing), decided to install the newer one; so I did:
# apt-get install postgresql
Then made various attempts to upgrade the clusters (as I could not clearly
understand the suggestion made by the install dialog):
# pg_upgradecluster
# pg_upgradecluster -v 8.3
# man pg_upgradecluster
# pg_upgradecluster postgresql-8.3
# ls /var/lib/post*/8.3/main
# ls /var/lib/post*/8.1/main
# pg_upgradecluster -v postgresql-8.3 postgresql-8.1 8.3/main /var/lib/postgresql
# pg_upgradecluster -v postgresql-8.3 postgresql-8.1 8.3 /var/lib/postgresql
# pg_upgradecluster -v postgresql-8.3 postgresql-8.1 /var/lib/postgresql/8.3/main
# reboot
# pg_upgradecluster -v postgresql-8.3 postgresql-8.1
# pg_upgradecluster -v postgresql-8.3 postgresql-8.1 /var/lib/postgresql/8.3
# pg_upgradecluster -v postgresql-8.3 postgresql-8.1 /var/lib/postgresql/8.3/main
# pg_upgradecluster 8.3 main
# pg_dropcluster 8.1 main

_and finally, the correct one_:

# pg_dropcluster 8.1 main --stop

[There was no output information/warnings on the console and, after
googling a while, I think there should be some]

At this point, on the assumption (after running partially my own script) that
everything worked as before, I removed old 8.1:

# apt-get remove postgresql-8.1 postgresql-client-8.1

I shouldn't have done that, because when I tried again to connect to my databse
I got strange warnings like:

2008-02-11 18:43:00 CET LOG: could not load root certificate file "root.crt":

Now the situation is as follows:

# ls -a /var/lib/postgresql/8.3/main

total 44
4 base/ 4 pg_multixact/ 4 pg_twophase/ 4 postmaster.opts 0 server.crt@
4 global/ 4 pg_subtrans/ 4 PG_VERSION 4 postmaster.pid 0 server.key@
4 pg_clog/ 4 pg_tblspc/ 4 pg_xlog/ 0 root.crt@

# ls -a /var/lib/postgresql/8.3/main/base

total 28
4 1/ 4 11510/ 4 11511/ 4 16385/ 4 16386/ 4 16387/ 4 16388/

# ls -a /var/lib/postgresql/8.3/main/global

total 288
8 1136 16 1233 16 2397 8 2694 8 2843 4 pg_auth
16 1137 8 1260 16 2671 8 2695 0 2844 8 pg_control
8 1213 0 1261 16 2672 16 2697 8 2845 4 pg_database

16 1232 8 2396 16 2677 0 2842 8 2847

so I suspect my data are still there, but wouldn't make things worse trying to
access them not knowing exactly how to do that, if possible!

Could you give me some hints?

Thanks for your attention.
Regards,
