Changing Tires at 100mph: A Guide to Zero Downtime Migrations
Postgres has some less robust tooling, at least both of these carry the "experimental" tag:

Show HN: Zero-downtime PostgreSQL migrations for Ruby on Rails
This is very cool! I no longer work on Rails on daily basis, but would have loved to have this.
I built something similar called `pg-osc` / `pg-online-schema-change` for PostgreSQL workloads. It does zero downtime migrations using triggers and shadow table.

Also love that this is written in Ruby :). Going to check it out on some side projects.

Pg_branch: Pre-alpha Postgres extension brings Neon-like branching
Underlying DBLab Engine is FOSS (Apache 2.0), with API, CLI and UI https://github.com/postgres-ai/database-lab-engine
-
Want to avoid MySQL but find PlanetScale really appealing
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".

Neon – Serverless Postgres
Agreed, this direction is underestimated and should be developed better -- we (Postgres.ai) do it for any Postgres with our Database Lab Engine [1], and Neon would bring even more power if it's installed on production
