You may be correct, but SYSCONFDIR (defaulting to /usr/etc) is used in some places at least in the client. This doesn't seem to affect postgresql.conf apparently, as I originally assumed. In general, strace -e open is insufficient for such tests, as virtually all programs will stat() a file before trying to open() it. When proving a file is not being checked, add the stat system call, too.
