> What features postgres offers over sqlite in the context of running on a single machine with a monolithic app The same thing SQL itself buys you: flexibility for unforeseen use cases and growth. Your SQLite benchmark is based in having just one write connection for SQLite but all eight writable connections for Postgres. Even in the context of a single app, not everyone wants to be tied down that way, particularly when thinking how it might evolve. If we know our app would not need to evolve we could really maximize performance and use a bespoke database instead of an rdbms. It seems a little aggressive for you to jump on a comment about how it’s reasonable to run Postgres sometimes with “SQLite smokes it in performance.” That’s true, when you can accept its serious constraints. As a wise man once said, “Postgres is great and there's nothing wrong with using it!”
