alt Hacker NewsHello, the developer of db9 here. You’re right, that section is indeed a bit too brief. We will add more architecture documentation later. What I wanted to convey is that, unlike a standard PostgreSQL, db9 is more like a pg SQL-compatible layer built on top of a large distributed KV store. I also shared a brief introduction in this tweet, which might help clarify things. https://x.com/dxhuang/status/2032016443114733744

If you're using TiKV why not use TiDB too, which is MySQL compatible?

"Compatible" isn't mentioned on the homepage, though, despite multiple opportunities to do so -- "Create, manage and query serverless PostgreSQL", "Run history, status, and metadata live in Postgres", "Full Postgres. Fully typed.".
This lack of detail may cause folks to form the incorrect impression that this is PostgreSQL, or a fork of it, or some module or plugin for it. Folks will be upset to learn that they were misinformed. Some will assign deception as the cause, whether that is true or not.
I think your interests would be best served by trying to make that distinction clear and prominently so. So for example "A PostgreSQL-compatible, fully serverless database", or similar.
I hope I have explained better.
