I'm using Loro as the CRDT as well as Iroh for byte transfer, works well. You can look at ElectricSQL as a Postgres sync engine but it won't do conflict resolution for you and it's hard doing CRDT operations on relational databases on general.

Look into these as well:

Same author, not necessarily sure why it's on two different domains with different content but they open sourced their sync engine. If you're interested in this topic, I'd follow. Their newsletter as they have great stuff.
