Database Import/Export on the Web

[vHrqO]

According to #3511

To import a database, we can use WasmDatabase.open and initializeDatabase.

However, for exporting a database,
it seems that we currently need to manually check for the implementation using WasmDatabase.probe,
and use IndexedDbFileSystem, SimpleOpfsFileSystem, to handle the export. Is that correct?

Or is there another recommended method?

It's true that you would have to create the VFS directly and use raw operations to extract the database - I'll look into creating an API on WasmProbeResult for that.
