I don't doubt what you are saying, but I just wanted to point out one thing: Postgres is amazingly forgiving, and performs incredibly with just basic adjustments to the default configuration. Give it a good amount of memory, and it will handle the vast majority of workloads extremely well. I have been using Postgres basically out of the box for a few years now for Data Warehousing purposes, and its performance is comparable to the tuned-and-managed Oracle servers that I am pulling from.
Reddit obviously is a different scenario, but most people don't work at Reddit.
