While these modules are really nice and helpful, we can't use them for at least 2 reasons: - for us, Postgres runs in a container on a private Docker network (`--network=matrix`) without usually being exposed to the host. These modules execute on the host so they won't be able to reach it. - these modules require `psycopg2`, so we need to install it before using it. This might or might not be its own can of worms.
