Postgres is not a distributed system in this configuration usually though is it?

The result is for “Amazon RDS for PostgreSQL multi-AZ clusters” which are certainly a distributed system.

I’m not well versed in RDS but I believe that clustered is the only way to use it.

An RDS cluster can have a single instance (but it can't be multi-AZ with a single instance.)

No, you can have single instances

This writeup tested multi-AZ RDS for Postgres — which is always distributed behind the scenes (otherwise, it couldn't exist in multiple AZs).

A multi-AZ cluster is necessarily a distributed system.
