// This is a driver for better-sqlite3. It may be interesting to use it instead
// of node-sqlite because it breaks all the time when we try to compile any app.
// The performance improvement probably won't matter.
//
// The issue however is that better-sqlite3 uses the option SQLITE_DQS=0, which
// disallows using double quotes around strings, and that's what we're using
// everywhere. So the only way to make it work would be to do a custom
// compilation, as described there, and set SQLITE_DQS=1:
//
