That is specifically about AWS/RDS and relates to EBS/IOPS moreso than PostgreSQL. In fact their solution was to run the db but not as an RDS instance. > The Solution: Roll your own: For us the solution was fairly simple: don’t use a managed database services and roll our own infrastructure on EC2. I've done the same running PostgreSQL on EC2 instances with NVMe local raid storage. It's very fast, but then you're responsible for its uptime, updates, backups, etc. That setup was used for performance sensitive but less critical data.
