I use docker (well, podman) for postgres on my personal machine because it's the one package that causes me headaches in my rolling release distro. Postgres n -> n+1 always requires a migration process (and you can't shortcut n -> n+x), so if I spend a period of time not working on my Postgres using projects, I find I've updated from n -> n+2 or more and need to figure out how to get the old version installed again since it's a dependency of the migration tools to have both versions available.
