Sorry, I still don't understand that. What is the "corresponding logical
log" ?
It seems to me, that a full page WAL record has enough info to produce a
dummy LSN WAL entry. So insead of just cutting the full page wal record
you
could replace it with a LSN WAL entry when archiving the log.
Then all that is needed is the one flag, no extra space ?
