Hi Neels,

This error states that the db user and db password that OpenERP server is using to connect to postgres is wrong. i.e check the server configuration file for the db_user and db_password are same as your postgres user and password.

Thanks,

try this
$su postgres
$psql
*alter user openpg with password admin;
and go to odoo config file and write (db_password = admin

On Linux, you have to create a specific user within the database to allow openERP to access the database.

Command (on Linux) to create a user within postgreSQL:

createuser --createdb --username postgres --no-createrole --no-superuser --pwprompt openerp

You probably have to do something simular on Windows

Hi,I know this is an old post but upper results are not working for me.Well this will definitely work.
You can see this django link => "https://stackoverflow.com/questions/34264003/peer-authentication-fails-with-postgressql-in-celery-task".

Apparently there are multiple ways for authentication with postgresql.

So,if your Postgresql user is different from your linux user then one easy way is to add `--db_host` to `localhost` which is `"127.0.0.1"`:

.odoo-bin -r "pg_user" -w 'pg_pass' --db_host
