It's boring but the last thing you want is excitement over data that's important to your business!
All the eng. managers I've worked with in the last decade have sworn by Postgres, in the decade before that they were swearing at mongo and getting betrayed by Arangodb switching to a restrictive license and seeing other innovative databases going down the same path means for new side projects I go postgres.
I've come to this conclusion too. It's a bit disappointing. I fully realize this is more than likely just user error. And now with AI agents the maintenance of a Postgres instance is likely less of a burden. But I can't help but yearn for the simplicity of a single SQLite file and bespoke solutions for things like queues, pub/sub, caching, etc.
