I was configuring odoo with database that I created from postgresql directly and all went good.

For reasons that I haven't could find the answer odoo don't have an option to delete/deseable demonstration data, only you can avoid demonstration data if you create the database from odoo database manager.

For this reason I create a new database from odoo database manager without demonstration data, but this second database I deleted from postgresql not from odoo, but now odoo is giving a lot of error and I have cannot connect to my first database anymore.

Anyone have an idea, why is this doing and how can I solve?

Please, dont say reinstall odoo and create another database, this is the last option.

Bellow the output errors:

$ python odoo.py --db_host localhost --db_port 5432 -r odoo -w odoo -d odoo-9 --xmlrpc-interface localhost --xmlrpc-port 8072
