> Aiming for postgres compatible database with a 2026 architecture

Except you didn't improve the architecture, did you? You just asked an LLM to copy what was already there. Making real improvements to the database architecture requires understanding the database architecture, not just asking a calculator to do the work for you.

Better benchmark performance means nothing if the underlying guarantees break, and a 300x improvement sure makes me suspicious. I would look at something like this if it passes a Jepsen test, otherwise you simply will not be able to convince me that it's worth my time.
