neon
Neon: Serverless Postgres. We separated storage and compute to offer autoscaling, code-like database branching, and scale to zero.
I recommend for you to check out https://neon.tech/, maybe their service fits your bill.

DBLab enables 🖖 database branching and ⚡️ thin cloning for any Postgres database and empowers DB testing in CI/CD. This optimizes database-related costs while improving time-to-market and software quality. Follow to stay updated.
That said, there are a few folks out there attempting it. As mentioned, Neon attempts branching but has no "merge". Postgres.ai has "thin clones" for similar migration testing but again, no "merge".

A lot of this is possible thanks to the magic of Vitess.
