Yes, but you must also backup the WAL archive from which you are
recovering (in case you are using file based log shipping and not
streaming replication). For streaming replication I don't know if it works.
Also you should check if postgres really stopped, since on high load
even the fast option can fail to stop it. Look here on how to do this:
