I just learned of Neon a few weeks ago. From the looks of it, Neon supports branching, but it doesn't support merging. Xata supports both branching and merging, however it only applies to the schema.

Dolt (and eventually DoltgreSQL) handles everything. Branching, merging, diffing, cherry-picking, commits, and more. Working with both the schema and data. On top of that, we also have DoltHub (https://www.dolthub.com/) that's analogous to GitHub, and DoltLab (https://www.dolthub.com/#doltlab) that's analogous to GitLab. We are targeting the entire ecosystem from the bottom up.
