We're Building Postgres in Rust. Using the LLVM of Databases

I'm already quite excited about Turso being SQLite-compatible, but adding many features on top.

And when a feature is not directly compatible with SQLite (ie: you can't directly read the file with `sqlite3`, it's straightforward to convert). This is great because you know you'll always be able to continue working with that database. Even if Turso stopped working, it's still a valid SQLite database.

A combination I would be excited about is:

- Full support for Postgres protocol/wire format (ie: Postgres, but in-process, backed by a single file). - Optional: Client/server architecture for further scaling and remote management using existing Postgres tooling - All backed by a SQLite-compatible file

They are already adding MVCC to SQLite anyway. So their effort seems doable, and I hope they succeed.

Sounds cool but also why? Is it so it's possible to have 1 database and then switch from sqlite to postgres without data migration?

Author also discussing it on their Twitter [0]. I’m reserving judgement for now, but this has lots of potential usecases even apart from replacing postgres.

The llvm of databases is not turso, it's datafusion.

Will it have fast COUNT-s?
