I find a solution to short the recover time by configure parameter Synchronous Transfer. Refer to : https://wiki.postgresql.org/wiki/Synchronous_Transfer. But I don't which postgreSQL will enable this parameter, I install 9.3.3-1 on redhat, but I don't find this parameter in postgresql.conf. Is there anyone use this parameter?
