A Vertica superuser is a database user—by default, named dbadmin—that is automatically created on installation.
A Vertica superuser is a database user—by default, named dbadmin—that is automatically created on installation. Vertica superusers have complete and irrevocable authority over database users, privileges, and roles.
Important
Vertica superusers are not the same as Linux superusers with (root) privileges.Superusers can change the privileges of any user and role, as well as override any privileges that are granted by users with the PSEUDOSUPERUSER role. They can also grant and revoke privileges on any user-owned object, and reassign object ownership.
Note
A superuser always changes a user's privileges on an object on behalf of the object owner. Thus, thegrantor setting in system table V_CATALOG.GRANTS always shows the object owner rather than the superuser who issued the GRANT statement.
