I recently did some db maintenance on a write heavy workload and I found that eventually it will bloat over time with a table with 500 million records. Switching it to use a proper partitioning scheme helped a lot. So people should not read this and assume you can just dump massive workloads into pg and they will be screamingly performant without some tuning and thoughtful design (I don’t think this is what you are implying, just a PSA)
