@cybrosys That is not the screen that was shown.  I said above, this is the screen that was shown when installing Odoo, whereas you have stated that your screen is shown after creating a master password.  The question again:

1.  What is the purpose of the master password?  Is this a password in Postgres, or something that Odoo keeps internally for some purpose?  If so, what purpose?

2. Why is Odoo giving me a master password on the installation screen, then immediately giving me a blank to enter that password and/or change it?  Am I supposed to enter the master password they have shown me, or am I supposed to enter a new master password?  In any event, an entry is mandatory.

3. What is the database you are referring to in #2?  Is this the postgres database that the postgres installer created when Postgres was installed?  In that case, wouldn't Odoo know that the name is postgres?   If Odoo needs another database, wouldn't the install docs say that I should have created that database in Postgres first?  If Odoo is going to create another Postgres database and is asking for the name of the new Postgres database, why wouldn't they make that clear?   In any event, it is very unclear what is going on.

4. Email will be login to my db?  Again, the install docs do say that I need to create a new Postgres db, and that odoo cannot use the postgres db.   I also think that I was supposed to create another Postgres user called odoo because odoo is not allowed to use the main postgres user, which is also called postgres, not openpg.  It is a real mystery where openpg came from.

5.  You can probably see that if I don't know the answers to the above four questions, I have no idea what password they are asking for in the blank between email and Phone number.

I don't know what or where the odoo conf file you refer to is.  The install instructions say merely to download the nightly exe file and run it. I don't have enough karma to post the link, but it is at www dot odoo dot com slash documentation slash 17.0 slash administration slash on_premise slash packages.html then scroll down to Windows.

I would unmark your answer as the correct answer, but I do not have enough karma to do that.  Not sure who marked the answer as correct, because it isn't.

Hi Harold Anderson  ,

• You can Change the pg_hba.conf file below,
  

host    all             all             0.0.0.0/0            trust

It was worked for me.

Thanks
