The log is getting from PostgreSQL 9.0.4
Basically we set up streaming replication hot-standby slave while master is under heavy load
The slave started but not accepting read-only queries,
every request will trigger the "FATAL: the database system is starting up" error.
The slave will eventually be able to accept read-only queries after the load on master is removed.
We don't see the same problem if we set up hot-standby slave while master is not under heavy load.
the logs follow:
