CRDT-richtext: Rust implementation of Peritext and Fugue
Cool, I'll check out your repos. Supabase also as Postgres CRDT (https://github.com/supabase/pg_crdt).
But, in general, I think searching in and across documents and database storage is going to a thorny problem even with existing, hyper-optimized CRDT algorithms. For example, if you just store your Yjs document as a binary blob in a Postgres column, Postgres becomes the bottleneck and all the fancy range-tree or b-tree optimizations are no longer that helpful on the server. Plus, it'd be great to have an document edit just be a tiny insert into the database that can be streamed to other clients rather than a big row update.
This all may because the focus of CRDTs seems to be rooted in a fully decentralized, P2P system but many developers want collaborative text editing in a more traditional client-server model.

A Yjs provider that uses Supabase Realtime for synchronization. Feedback / suggestions welcome.
I'm part of the Supabase Realtime team. Thanks for doing this! We've been wanting to do it internally ever since launching Broadcast. We've also been experimenting with what a very integrated CRDT solution looks like (e.g. pg_crdt).

Show HN: Pg_CRDT – an experimental CRDT extension for Postgres
This is an experimental extension for CRDTs, `pg_crdt`[0]. It supports Yjs/Yrs and Automerge.
The linked blog post describes how we're thinking about this extension in a Supabase context. Ideally this "Show HN" generates some discussion/interest, both here and in the github discussions [1].
I want to emphasise this part from the blog post[2]: "pg_crdt has not been released onto the Supabase platform (and it may never be). We’re considering many options for offline-sync/support and, while CRDTs will undoubtedly factor in, we’re not sure if this is the right approach."
