This runs fine as my normal user: `cd /opt/odoo; python openerp-server --addons-path=addons`
But when I want to run it as another user, e.g. through
sudo su odoo -c "cd /opt/odoo; python openerp-server --addons-path=addons"
I get this error: `OperationalError: FATAL: role "odoo" does not exist`
I found out it breaks less after `createuser odoo` but then my existing installation is not there anymore. What is a smooth way to change the user running the process? Where is the database configuration?
How come it's breaking for odoo while it's working for my normal user and how to fix it?
Are there other things to change as well?
