Except that http://crbug.com/27938 seems to be going the route of
displaying a prompt that let's the user decide whether to remove
LocalStorage data on extension uninstall.

The original poster wants a method that is guaranteed to remove the
LocalStorage data and well as delete data from a SQLite database.

That's why Aaron suggested needing oninstall and onuninstall hooks.

I think the requirement here is different from http://crbug.com/27938
