I experienced the same on a Windows machine with Odoo 17. The cause of this problem could be that you installed Postgresql before installing Odoo.
How I solved it is by the following:
I uninstalled Postgresql and deleted all folders in installation path (in the C drive) and pgAdmin folder in AppData folder (it's usually a hidden folder located under Users folder). Then I uninstalled Odoo.
Finally I re-installed Odoo 17, and during this step I selected the option to install Postgresql.
If you already have an existing database, make sure to make a backup of it and Odoo modules.
