Subject: [PATCH] Disable full_page_writes, because turning it off risks
causing crash-recovery failures even when the hardware and OS did nothing
wrong. Per recent analysis of a problem report from Alex Bahdushka.
For the moment I've just diked out the test of the parameter, rather than
removing the GUC infrastructure and documentation, in case we conclude that
there's something salvageable there. There seems no chance of it being
resurrected in the 8.1 branch though.
