Tom gave instructions in a mail (to you I think) to patch the xlog.c
file so page dumps stop happening. I'm too lazy to search for that mail
(I deleted my local copy) but if you find it in your mailbox, resend it
to me and I'll produce a patch for you to test. (I'd produce the patch
myself but I don't know the xlog code well enough to find the right spot
quickly.)
