Delete existing databases with the refdba command deletedb foo.
| Warning |
The contents of the database as well as the database structure will be gone completely. This is different from deleting all datasets. The latter will leave the database structure intact so you can add references again. The former will force you to create a new database before you can add references again. |
Usually this command also removes any permissions to the given database that you have granted to users. If you re-create a database with the same name later, you will have to grant permissions again.
