Make sense, removed in the attached version.

I think yes, it will be the same as you are suggesting a shutdown
which eventually performs a checkpoint. That checkpoint on the
recovery server performs the restart point instead. Still, there could
be a case where archive_cleanup_command execution could be skipped,
if there is no record replied after the previous restart point, which
could happen in case of shutdown as well. Hope that makes sense.
