The author argues against architectural cargo culting by demonstrating how to build a complex financial system using only PostgreSQL, leveraging advanced features like constraints, triggers, and serializable isolation. This approach aims to reduce operational complexity and system entropy by eliminating the need for additional specialized databases or caching layers.
Background
Modern microservices architectures often lead to over-engineering by adding multiple specialized tools for tasks that relational databases can handle natively. This article challenges that trend by providing a practical, first-principles example of a robust OLTP/OLAP hybrid system within a single database engine.
