Passing undefined values to InsertQueryBuilder.values doesn't fallback to defaults.

First of all, thank you for writing this lightweight TS safe library. We're migrating our website from MongoDB to PostgreSQL. We tried Prisma and it was a hot pile of disaster in terms on performance.

However, while setting up a few scripts, we found a bug inside this library. Our hands are currently full otherwise would have loved to jump into source and send a PR fix too. Here's how you can reproduce the bug:

1. Go to https://codedamn.com/playground/4rv-jRRmU-BdpcEtjKm-0
2. Click on "Run code" button on top right
3. Go through the comments in the codebase

Hey 👋

Thank you for the reproduction code!

Thanks for quick feedback. Note that this bug also exists on postgres dialect (saw that you labeled it as sqlite).
