Details:

After working around the python-xml issue (bug 337759), i tried starting openerp via
  service openerp-server restart
which didn't work:

The funny thing is that starting /usr/bin/openerp-server worked like a charm.

I tried playing with pg_hba.conf, but couldn't fix it.

Google pointed me to
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=516348#15

and the same bug (comment #15) is present in the ubuntu package: $USER is used for the chuid parameter in the init-script, but never defined/initialized.

Adding USER=openerp fixed the issue for me.

(The following settings must point to the same user (for ident sameuser in pg_hba.conf) to work:
* database user in PostgreSQL (see README.Debian)
* db_user in /etc/openerp-server.conf
* $USER in /etc/init.d/openerp
)
