Currently the binding for approximateSize stores the result as uint32 (

). This supports only databases of up to 4GB and returns wrong results for larger DBs.

It would be nice if approximateSize could either

1. support all of Number.isSafeInteger(),
2. support larger numbers by representing them as nearest float (it's "approximate" after all),
3. return BitInt, or
4. at least return an error if an invalid result is returned.

Not sure, which of the options would be best.
