If you use the RPM packages from the PostgreSQL download page, as I would recommend,
a user "postgres" will be created automatically.

You can of course remove the user again, but you will need a user different
from "root" to run PostgreSQL.

PostgreSQL will refuse to start under the "root" user for security reasons.
It is not commendable to run any software as "root" unless absolutely necessary.

Mind you, "postgres" is *not* the owner of the executables (this is not Oracle), but
the owner of the database files and processes.
