http://www.postgresql.org/docs/9.1/interactive/warm-standby.html#STREAMING-REPLICATION

"Streaming replication allows a standby server to stay more up-to-date than is 
possible 
with file-based log shipping. The standby connects to the primary, which 
streams WAL 
records to the standby as they're generated, without waiting for the WAL file 
to be filled."
