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,

Package: postgresql

When I first configure operating-system with postgresql-service with default config file, then run

guix system reconfigure config.scm,

then configure operating-system with postgresql-service with custom config file, then run

guix system reconfigure config.scm,

I get:

---
initdb: directory "/var/lib/postgresql/data" exists but is not empty
If you want to create a new database system, either remove or empty
the directory "/var/lib/postgresql/data" or run initdb
with an argument other than "/var/lib/postgresql/data".
making '/gnu/store/byn534fg4agm0vv9szl5kkfl19n080b2-system' the current system...
Installation finished. No error reported.
----

Postgresql doesn't run and the error message still references the default config file.
