nix: Do not start PG if running In a nix hook the PG server is started when `nix-shell` is invoked. This created extra output when nix-shell was invoked on an extra shell as it tried to start a new PG server again while it was already running. This change updates the behaviour to not do this, and verify with pg_ctl if PG is already running.

When `nix-shell` is in your `$PATH`, execute: `nix-shell`. Nix will download and
manage dependencies for you. Nix will also start a postgresql server and initiate
the database.
