Subject: [PATCH] PostgreSQL: Don't specify a default PostgreSQL package

The user should specify which major version to use
(e.g. "services.postgresql.package = pkgs.postgresql92").  We can't
really provide a sensible default, because such a default would have
to be updated from time to time, and there is no automated upgrade
procedure.  So leave upgrading to the user.
