The reason the RH packages use /etc is that there's a distro-wide default
that configure gets invoked with --sysconfdir=/etc unless the packager
takes steps to override that. The RH postgresql packages *did* take steps
to override that, up till about Fedora 16/RHEL7 --- before then the
arrangement was --sysconfdir=/etc/sysconfig/pgsql. So David's comment
isn't even correct for the majority of Red Hat installations today.
Between that and your points about PGDG and Debian, it's clear that "/etc"
is wrong far more often than it's right.
I'd suggest wording along the lines of
... or it can be a system-wide file, which is named
<filename>pg_service.conf</filename> and located in the directory
specified by the environment variable <envar>PGSYSCONFDIR</envar>.
If that variable is not set, the system-wide file is sought in the
directory displayed by <command>pg_config --sysconfig</command>
(by default, <filename><replaceable>installprefix</>/etc</filename>).
However, I don't know whether that advice also works for Windows;
can anyone check?
