Thanks for your feedback, I already did some changes like typos and yum install…
My testsystem was not that good, many packages installed, tested other software, so I’ll go through the howto with a fresh installation the next days…
Builtin server of Odoo just does http, so there’s another mission with nginx proxy:

I created a user with phppgmyadmin without a database, so I got the db creation screen.
Maybe you did the command line way with creating role and db so no db creation screen, would make sense.
Important is the user, as user postgres is not allowed, it seems like the DB will be created, just when necessary.
