Thanks all.
Now understand LSN strongly connected with WAL.
However how difficult put last system LSN instead 0?
It's not so important but will allow make use LSN more consistent.
Maybe explain why you're interested in page lsns, that'd perhaps allow

Yeah, especially since you mentioned this being for backups. I suspect
you *want* those WAL records marked with 0, because that tells you that
you can't rely on WAL when you back that data up.
