Agreed, thank you a lot! Yes, "...or fetched on startup" looks a bit
confusing for me, since the whole paragraph is about target server
before running pg_rewind, but this statement is more about target server
started first time after running pg_rewind, which is discussed in the
next paragraph.

I have reworded these and some similar messages, thanks. New patch with
changed messages is attached.

I don't like it either, but this one was my best guess then. Maybe
--restore-target-wal instead of --using-postgresql-conf will be better?
And --target-restore-command instead of --restore-command if we want to
specify that this is restore_command for target server?
