Well, doing a proper service shutdown involves replacing the homepage
with something saying "We're updating the database, please come again
in one hour". It's also complicated in some way.

The issue in my proposal is more on access rights, because it means
that the script must be allowed to create new databases on the
PostgreSQL server.
