Yup. I've got a (legacy) postgresql database with time series: one timestamp plus measurement per row. And there's a useless third column too. It's awful, and sluggish.
For a newer project, where we basically use one object, I've chosen a NoSQL database. Get the object, edit it in the browser, put it back. Done. No need to update relations, ORMs or any of that. But: that won't fly for more complex projects.
So I agree: pick the right tool for the job.
