k, why are you concerned? see my other message, but if the major concern
is the xlog directory for a postmaster, then put in a consistency check
for when starting ...

then again, how many out there are running multiple instances of
postmaster on their machine that would move xlog to a different location
without realizing they did? I know in my case, we're working at reducing
the # of instances on our servers to 2 (internal vs external), but, our
servers are all on a RAID5 array, so there is nowhere to really "move"
xlog to out then its default location ... but I can see the usefulness of
doing so ...

Myself, if I'm going to move something around, it will be after the server
has been running for a while and I've added in more drive space in order
to correct a problem i didn't anticipate (namely, disk I/O) ... at that
point, I really don't wan tto have to dump/re-initdb/load just to move the
xlog directory to that new drive ...
