Yes, I got this concept from the commit message, but I am unclear on
what is actually happening so I can clearly explain it.  Slot creation
on the standby needs a snapshot, and that is only created when there is
activity, or happens periodically, and this forces it to happen, or
something?  And what snapshot is this?  The current session's?
