Thank you, I verified and notices that the Odoo (all in One) installes the postgre binary but did not initialized the DB and also did not installed the service "postgre". I don't know if this is a problem of windows 10. May be other users can confirm this?

However I collected several information how to initialize postgresql and how it can be installed as a service from different sites on the internet.

finally I could it get running by following these steps:

1. Open cmd line environment with Administrator privileges

2. got to postgresql isntallation from odoo e.g.: cd "C:\Program Files (x86)\Odoo 9.0-20161005\PostgreSQL\bin"

3. initialize the postgresql server with the credentials you have entered during the odoo installer

initdb.exe --locale=German_Germany -E UTF-8 -U openpg -W "C:\Program Files (x86)\Odoo 9.0-20161005\PostgreSQL\data"

Remarks: please make sure that the data directory is empty. please use your "locale" according your platform. the -U is the option to create a superuser with that name while -W will prompt you for the password for this new user.

4. register the "postgres" service: pg_ctl.exe register -N postgres -D "c:\Program Files (x86)\Odoo 9.0-20161005\PostgreSQL\data"

5. start the service in the windows mgmt console

6. after that you should be able to access the odoo page and start with the DB installation

Hope this helps
