Log message:
    Add code to apply some simple sanity checks to the header fields of a
    page when it's read in, per pghackers discussion around 17-Feb.  Add a
    GUC variable zero_damaged_pages that causes the response to be a WARNING
    followed by zeroing the page, rather than the normal ERROR; this is per
    Hiroshi's suggestion that there needs to be a way to get at the data
    in the rest of the table.
