Automated Deployment of PostgreSQL Ha Clusters Anywhere
Creating a robust and reliable database cluster is often fraught with challenges.A manual deployment process can be fraught with risks, particularly for those who lack extensive experience. Even minor errors in configuration can drastically affect your database's performance and stability.
Recognizing this intricacy, many businesses choose to use cloud-based managed databases. These services offer convenience but not without limitations. These drawbacks can include being tied to a specific cloud provider and limited direct access to the database server for adjustments. These constraints can hinder your ability to tune your system and perform thorough performance analyses.
In response to these challenges, we've developed a project to make this process easier and more efficient. This project uses automation to streamline the deployment of High-Availability PostgreSQL Clusters. By doing so, it helps mitigate the risks involved with manual configuration and speeds up the deployment process.
Our solution caters to various deployment environments. It allows you to establish your cluster either in your own data center or in the cloud, providing a robust database solution similar to managed databases, but with you retaining full control.

- Citus: PostgreSQL extension that transforms Postgres into a distributed database

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.
