I remember Greg Mullane posted a tool that attempts to correct page CRC
mismatches[1].  This new tool might be useful to feed healing attempts,
too.  (It's of course not in any way a *solution*, because the page
might have been modified by other WAL records since the last FPI, but it
could be a start towards building a solution that scoops page contents
from WAL.)
