Hello Takayuki,

Sorry can you explain how we can same network bandwidth by not sending the WAL archive from the primary to the standby(s).
I possible scenario is have to multiple standby servers in same host for same master. or other scenarios exists ?

Before  archive_mode = always became available, we've had to stream the WAL twice, once to the hot standby for immediate application, and once to pg_receivexlog for archival purposes.  So it doubled the bandwidth usage.
 
Cheers,

Jeff
