Looks like you have set the wrong host information in recovery.conf file or there is a mistake in recovery.conf file. Please check your recovery.conf file.
May be postgres should throw a correct message to the logs saying the host information for replication is wrong or something meaningful to understand instead of "database system identifier differs between the primary and standby"
Thanks
