That's intentional. We may be able to make XLOG_SWITCH records as not
updating the progress LSN, but I wanted to tackle that as a separate
patch once we got the basics done correctly, which is still what I
think this patch is doing. I should have been more precise upthread:
this patch makes the handling of checkpoint skip logic correct for
only standby snapshots, not segment switches, and puts the infra to
handle other things.
