There are actually three assumptions underlying "by default":
1. You haven't changed the default search_path setting.
2. You haven't created a schema matching your own username.
3. You haven't removed the public schema.
The section after this one goes into these details. I don't think that
explaining them all right here would be an improvement in readability.
You have to start somewhere ...
