I also added a mention that rsync, not pg_upgrade, will be run on the
standbys.  You can see all the results of the patch here:

Thanks.


Sweet, I'm glad I stopped where I did.  I think I'm safe to pick up at step f.  
Which seemed to work ok.  But now we get to step g (run rsync).  I checked the 
rsync manual and don't see anything like this three directory argument thing 
you are trying to run.  Unless you want to use --link-dest.  In which case I 
think the cmd would be like:

rsync --archive --delete --hard-links --size-only --link-dest=old_pgdata 
new_pgdata remote_dir

I'm gonna try this now, will report back.

No, you are copying "old_pgdata and new_pgdata" to remote_dir.


Ohhh... I'll try again.  (The method above (run from the standby) doesn't work 
well at all).
