I do this using the Docker approach, especially for low scale web apps that run on a single VM. I like that its full Postgres versus the sometimes odd limits of SQLite. My usual approach uses a Trafik container for SSL, Django+gunicorn web app, and Postgres container; all running as containers one VM. Postgres uses a volume, which I back up regularly. For testing I use `eatmydata` which turns off sync, and speeds up test cycles by a couple percent.

I haven't tried the unix socket approach, I suppose I should try, but it's plenty performant as is. One project I built using this model hit the HN front page. Importantly, the "marketing page" was static content on a CDN, so the web app only saw users who signed up.

Yeah, basically the same here, except it's Caddy in front instead of Traefik.

So you do periodic backups, not incremental on every write or something (read replica-like)?

It's important to me to not lose any data once committed if at all possible.

(For testing, I've sped everything up by running migrations on `template1` and every test gets a random database name. Works wonders.)
