Debate Heats Up: Can PostgreSQL Truly Scale?

A heated discussion is underway among database engineers over whether PostgreSQL can scale effectively. In a recent exchange on HackerNews, engineers from DBOS and Temporal clashed on the topic, with one commenting, "Bad schema beats bad software every time." The debate centers on PostgreSQL's ability to handle large-scale workloads, with proponents arguing that proper schema design can overcome limitations, while critics point to performance issues. The conversation, which started as a YouTube Short, has sparked broader interest in the database community. As data demands grow, the question of PostgreSQL's scalability remains a key point of contention among developers and architects.
