If you're comfortable doing that, and plenty of folks are (especially us oldies who remember the shared hosting days), then that's a great way to go. I think that many who pull a docker compose file probably aren't ready to also be a PG admin, and if not shared, Postgres is probably overkill for most things. But, I've also had bouts of "just use a single PG/MySQL instance" myself. I get it.
