Figma's Databases team lived to tell the scale
I see they don't mention Citus (https://github.com/citusdata/citus), which is already a fairly mature native Postgres extension. From the details given in the article, in sounds like they just reimplemented it.
I wonder if they were unaware of it or disregarded it for a reason —I currently am in a similar situation as the one described in the blog, trying to shard a massive Postgres DB.

PostgreSQL Is Enough
It is possible, if you pay for it. You can do Multi-AZ Clustered Instances in RDS, where you get the benefits of Multi-AZ failover with traffic sharing.
If you can run your own infra – at least on an EC2 level – you can do things like Citus [0] for Postgres, which is about as close to "just add database nodes" as you'll get.

So while searching for something like this for postgres I came across citus. Any one know how that stacks up?

How to scale storage of PostgreSQL database?
Disaggregated storage for Postgres is still a very new technology, both with NeonDB and PolarDB (https://github.com/ApsaraDB/PolarDB-for-PostgreSQL).

Neon – Serverless Postgres
Amazing work by the Team. Congrats y'all. It was one of the best presentations in the PGcon22.
I did email Heikki the following questions, in case if someone from Neon is around here.
a) How does Neon compare to polardb https://github.com/ApsaraDB/PolarDB-for-PostgreSQL.
b) The readme mentions a component "Repository - Neon storage implementation". Does it use any special FileSystem? Any links to read more about it?
c) Heard the cold start is a second (IIRC), how does that value differ if one runs Neon on bare metal instead of k8s?
