Hi,
I am running a test setup for verifying the hot standby feature in Postgres 9.0 release. Both my Master (Win 7 Professional, 32 bit) & Standby (Win 7 Professional, 32 bit) machines are having Postgres 9.0 (postgresql-9.0.3-1-windows) installed & both are in our LAN environment.
After taking a hot backup of the master database using pg_start_backup() & copy of the data folder to Standby machine followed by pg_stop_backup() in Master, the Standby server is started. The Standby server logs show the following error and the Postgres server shuts down
