WARNING: psql version 8.4, server version 9.1

Hi all,

[using:
postgresql/wheezy uptodate 9.1+134wheezy1
postgresql-client/wheezy uptodate 9.1+134wheezy1
postgresql-client-common/wheezy uptodate 134wheezy1
Linux deby.ei.hnet 2.6.32-trunk-686 #1 SMP Sun Jan 10 06:32:16 UTC 2010
i686 GNU/Linux]

I upgraded pg_8.4 to 9.1 and run pg_upgradecluster but if I try to
connect with:
$ psql mydb -p 5433 (to make sure everything is ok) I get:

psql: FATAL: role "ennio" does not exist

su - postgres && createuser ennio, warns:

createuser: creation of new role failed: ERROR: role "ennio" already exists

Trying to ocnnect as postgres (psql -p 5433) I get the warning in
subject.

How to overcome this empasse?

Thanks for your attention. Regards,
ennio
