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).

Yeah, much better:

test1 is the primary, and test2 the standby. Both have /pub/pg93 and /pub/pg95
I copied over a recovery.conf and the standby started up.
I started pg95 on the primary and am running analyze now. I'll copy over wal to the standby and continue testing.
Looks good so far!
Thanks,
