Hello everybody,

We have Odoo 10.0 community edition installed on Ubuntu 16.04 VPS. We really like the system and its flexibility.
But today somethig very bad happened:
Our VPS provider restarted all servers and after restart Odoo database is gone. Logs doesn't say too much only that it could not connect to database. Postgresql logs doesn't say anything as well. Everything looks like it was working well and instantly everything dissapeared... Auth logs doesn't say that anything might went wrong as there is no suspicious actions there. Now when I check postgresql databases list there is no Odoo database in there and Odoo is asking for me to create new database. Why could that have happened? And is there any way to restore the database?

Here are the database logs:
