I should add: shortly afterwards, it got a little worse, and the
following directory inodes got clobbered:

/pgsql/data/global
/pgsql/data/pg_xlog
/pgsql/data/pg_clog
/pgsql/data/pg_notify
/pgsql/data/pg_serial

fsck repaired what it could, and re-attached a bunch of unnamed files
into lost+found - that's after a clean umount. I haven't even bothered
rebooting as yet.

Looks like postgresql committed suicide around
[22/Nov/2015:01:06:54 +1100] according to the apache logs. This seems to
coincide with the following rsync pulling from netbsd.org:

/usr/pkg/bin/rsync -azvC --stats --del --exclude CVSROOT \
--exclude htdocs --exclude othersrc anoncvs.NetBSD.org::cvsroot \
/home/netbsd/cvsroot/

That's way too much of a coincidence for my liking. Different file
hierarchy, but it's the same filesystem. I've now switched to using
--delete-delay, rather than --delete-during (aka --del), perhaps
that'll work around the issue?
