But after some minutes the master output:

the standby output:
FATAL: could not receive data from WAL stream: FATAL: requested WAL segment XXX

Question:
Why the master deletes the WAL segment before send to standby in synchronous mode? It is a streaming replication bug ?

master server output:
LOG: database system was interrupted; last known up at 2012-03-30 15:37:03 HKT
LOG: database system was not properly shut down; automatic recovery in progress
My question would be, what happened above? In other words what does the
log prior to this one show just before the database shutdown?
