This looks good to me. One small thing, though: maybe the comments
should not say anything about the REDO routine -- that seems like a
case of "the tail wagging the dog" to me. Perhaps say something like:

"Remove the last pivot tuple on the page.  This keeps things simple
for WAL consistency checking."

(Just a suggestion.)

Thanks!
