[Help] Questions migrating from sql.js

I'm currently migrating from sql.js to @db/sqlite and have a few questions:

1. Is it possible to export the database as a buffer, like `db.export()` in sql.js?
2. Can I check the size of the database, similar to `db.size()` in sql.js?
3. What is the equivalent of `{ useBigInt: true }` in sql.js for this library?
