I checked the database privileges and I found:

postgres=# \du
List of roles
Role name | Attributes | Member of
-----------+------------------------------------------------+-----------
postgres | Superuser, Create role, Create DB, Replication | {}
root | Cannot login | {}
other | Superuser | {root}

Is it correct?

Probably is very easy but I didn't find the solution.

Regards.
