Well, new Database create only isntanse of class.
But not FILES of db on disk or RAM.

So yes its important to call db.Create()

What happens if you do
    db.Create( "fake name" )
?

Does V4RB crate any disk files?
I think it should not create disk files because they will be created in RAM.

Name of course will be ignored.
