This avoids useless checkpoint activity if XLogWrite is executed when we have a very stale local copy of RedoRecPtr. The potential for useless checkpoint is very much worse in 8.3 because of the walwriter process (which never does XLogInsert), so while this behavior was intentional, it needs to be changed.
