Refresh my memory as to why we need to WAL-log hints for checksumming?
Torn pages:
So it's not that we actually need to log the individual hint bit
changes, it's that we need to WAL-log a full page image on the first
update after a checkpoint, so as to recover from torn-page cases.
Which one are we doing?
Correct. We're doing the latter, see XLogSaveBufferForHint().
