Haven't had a chance to look at this in depth but improving things here
would be good.
An additional thing that we should really be mentioning is to tell
people to go in and TRUNCATE all of their UNLOGGED tables before going
through this process, otherwise the rsync will end up spending a bunch
of time copying the files for UNLOGGED relations which you really don't
want.
