Then you haven't been paying attention, and no, that's not the right way
to do it. The PGDG RPMs, for example, support multi-tenancy very easily,
both for systems that use init scripts and those using systemd. I have
blogged about how to do this here:
<http://web.archive.org/web/20111127175231/http://people.planetpostgresql.org/andrew/index.php?/archives/233-Multi-tenancy-under-systemd.html>
and here
<http://web.archive.org/web/20111221072621/http://people.planetpostgresql.org/andrew/index.php?/archives/134-Multi-tenancy-done-right.html>
But in any case, it's largely irrelevant, ISTM. Anybody who actually
needs that message from initdb should almost be using pg_ctl instead of
calling postgres direct.
