When you're building a serverless web app, it can be pretty easy to forget about the database. You build a backend, send some data to a frontend, write some tests, and it'll scale to infinity with no effort, right? Not quite. Especially not with Postgres. As the number of users of your frontend increases, your app will open more and more database connections until the database is unable to accept any more. It gets worse.

September and October were relatively quiet, so I thought I would write a single article for both months. While I'd normally try to write at least one useful article per month for OnlineOrNot's audience (as well as an update on how the business is going), I wrote no articles, and no code, actually. Instead, I packed up my life in Sydney, Australia, escaped lockdown, and relocated to France with my wife, and just enjoyed living for a while.
