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.)
