Preferred way to clear/delete IDBFS database?

What is the preferred way to delete / empty / clear a filesystem persisted using IDBFS?

I've found the [deleteDatabase()](https://developer.mozilla.org/en-US/docs/Web/API/IDBFactory/deleteDatabase) and [clear()](https://developer.mozilla.org/en-US/docs/Web/API/IDBObjectStore/clear) functions that operate on an IDBFactory and IDBObectStore respectively, but there doesn't seem to be any way to get my IDBFS database name.
