Yes, this is a known limitation: <http://bugs.gnu.org/22039>.

Currently, for services that are safe to be restarted, the solution is
to explicitly stop them beforehand, in which case the new service gets
started by ‘guix system reconfigure’:

  # herd stop postgresql
  # guix system reconfigure new-config.scm

I’m closing this bug.  Let me know if anything else is amiss.

Thanks,
Ludo’.
