Yep. This is mentioned in the documentation:
http://www.postgresql.org/docs/devel/static/app-pgrewind.html
"The target server must shut down cleanly before running pg_rewind>>.
You can start old master, wait for crash recovery to complete, stop it
cleanly and then use pg_rewind. It works.
Shouldn't we have a flag so it does that automatically if necessary?
Might be handy, but currently pg_rewind never invokes postgres or other
binaries, so it would be a fair amount of new functionality to implement
that. Let's keep it simple for now.
