Nice, the pushback is about the default location, thanks for
supporting the idea :)

Seriously, debian package will install pg_xlog in $PGDATA which is
often not what I want. So first thing after install, I stop the
cluster, move the pg_xlog, setup a ln -s and restart. I figured having
to do the same for setting up archiving would make my day, when
compared to current documentation setup. Any better idea for a safe
enough default location is welcome, of course.

Oh, and I hope you didn't read that the archive mode be 'on' by
default in my proposal, because that's not what I meant.
