I've only worked with MySQL, Sqlite up until this year. Started on Postgres since January and I'm seeing how flexible it is.

Fixed by our agent. Thank you!

#13> db9 is a PostgreSQL-compatible distributed SQL database. Your data is stored in a distributed TiKV cluster, and each database (tenant) gets its own isolated keyspace.

Doltgres actually is a true versioned Postgres under the hood (or MySql).
This sounds really interesting, and I like the ease with which I could spin something up here and get embeddings for sure! But I would think the actual runtime perf of this would be “fine” for some text, but nowhere near Postgres level for all sorts of other stuff, right?
I am a huge fan of Postgres as a database, and of SQL, etc. but I don’t think I understand the benefit of using Postgres’ wire format here since it’s not Postgres behind the scenes. I guess that lets you use psql as the client?

Hello, 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/20320164431147337…
"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.

This is really interesting! Thanks
Re: Postgres with Builtin File Systems
#17I like the idea of combining the file system and the database. It's really useful when people don’t want to manage files and structured data separately.

PG compatible means if you built your application or analytics queries for PG SQL, it's very easy to migrate to XYZ database that takes PG SQL as input and returns the same results in most cases. The wire format means you can point your code at the database and get the same responses as normal SQL.
I agree with the commentary above that it's much clearer to describe something as "PG SQL/wire format compatible".

PG SQL is my favorite for many reasons after working with the other two for a decade+ at times. I can turn it into whatever database I want it to be, ultimately.

If you're using TiKV why not use TiDB too, which is MySQL compatible?
it has nothing to do with TiDB, db9 is built from scratch.A good way to think about it is that db9 is similar to tidb-server, it provides a PostgreSQL wire protocol and SQL layer, while the actual data lives in the underlying KV layer.
