I... just add it. How do I add it in heroku where everything is "just create an app and push it" and everything is separate "dynos" (whatever that is), each with different pricing, storage, bandwidth etc.

that is true. everything is a separate dyno - means separate machine/vm to which you need to connect to. You get free tier for almost all databases and you only need to know how to connect to it, not tinkering with the storage, tune the parameters, scheduled backups, automatic scalability etc - that's done for you. it will become expensive once you go past free tier or the cheap tiers though.

Thing is: if we're looking for free, that may make sense. you still need tinkering though: you need to figure out what the whole dyno thing is about and how to connect from one dyno to another, and so on.

However, if we expand this a tiny bit to cheap and/or free, then simply running the lowest-tier server at Digital Ocean will be a better proposition. And installing a database these days is basically the same thing: run a command to install, all you need is to connect to it. No tinkering. And it will still probably scale significantly better than a free tier at Heroku :)

Once again, I'm biased and old, and can afford to spend money on side projects. I know that sometimes even $15 a month is out of reach (oh, I've been there). But yeah, this sorta prevents me from ever understanding Heroku :)
