[Help] Questions migrating from sql.js

[CyanChanges]

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?
