Database in container solves a few problems for me: 1. I can start it and stop it automatically with Compose. That's a big increase in ergonomics. 2. I don't have to write my own scripts to set up and tear down the database in the dev environment. The Postgres image + Compose does all that for me. 3. Contributors who don't know much about Unix or database admin stuff (data analysts learning Python & data scientists contributing to the code) don't have to install or mess with anything. It works on everyone's machine the same way. Volume and port mapping are basically trivial concepts anyway. There's been zero downside for me in using it, even though I personally have the skills and knowledge to not "need" it. Why would I go without it? It saves me time and effort that could be significantly better used elsewhere.
