After searching a bit (cd nixos && git log --grep=postgres) I found
out that I have to select a postgresql package:

services.postgresql.package = pkgs.postgresql92;

Two questions:
- Is it not possible to have a default version?
- If no default version, is there at least a way to print a *human
readable* error message that hints the user about
services.postgresql.package? The error you get now is pretty horrible.
