May be its work for you.

You can find list of role(psql) using command-line

1)sudo su postgres

2)psql

3)\du

Check "openpg" is available or not. if its not that create new role.

Ok, It solved.

First of all i removed all postgreSQL from my Windows 10 and from registry. I removed Odoo 10, and installed it again with check box postgreSQL. What's all.

After it i had another issue: i put my modul in moduls folder but Odoo doesn't show it. I solved it just put all files in root modul folder.
