Correct me if I'm wrong, but the main reason for the WAL CRC is to
detect partial WAL writes (due to improper caching, for instance).
This means that you're out of the realm of traditional CRC analysis
anyway, because the things you are guarding against are neither burts
errors nor n-bit errors (for small n).
