Who exactly is the "dbuser"? Is it some live human user? Or is it an internal name and password that the wiki uses to connect to and interact with the database?
I don't understand what you mean by "If you fill in the superuser section with valid credentials, the database and database user do not have to be precreated,...." How can they be 'valid' if they're not already pre-existing??

wikidb and wikiuser are prefilled just to give the user an idea of what is expected, they do not have to be the same as the site config username and password. If you fill in the superuser section with valid credentials the database and database user do not have to be precreated, otherwise they must be (see the MySQL manually for details on how to do this, or consult your web host if you use one).
