Is it possible to use both an in memory and indexDB at the same time?

[TheOtherBrian1]

I defined two databases in the browser:

const cacheDb = new PGlite('idb://cache');

const db = new PGlite();

One was intended to be discardable for tests, while the other acted as a local cache.

They appear to overwrite each other. Only the second DB defined is accessible. Is it possible to have two different file systems?

They would need to run on different threads because otherwise they share the same runtime memory hence the overwrite behaviour, try to run both in their own worker so they get different memories.
