This type must not outlive the DBs and caches that are added to it, otherwise the caller will access invalid memory and likely crash. Use PhantomData to ensure it does not outlive its arguments. This is technically a breaking API change, but anything that used this code in this way was likely broken anyway. Co-authored-by: Oleksandr Anyshchenko <aanischenko@gmail.com>
