PG_STANDBY ISSUE - Mailing list pgsql-general

Hi experts -

                I am running into issue with pg_standby. May be my understanding is not correct. Please help. here is what I did .

1.     I made changes in the postgresql.conf  ( archive_mode = on ,archive_command = 'cp -i %p /opt/postgres/archive/%f' , archive_timeout = 60s )
2.     pg_ctl start -D $PGDATA -l /opt/postgres/logfile
3.    postgres=# select pg_start_backup('BKP_LBL');
4.    I have done the base backup  and I have used the following command for restore in the recovery.conf
5.   restore_command = 'pg_standby -d -s 3 -t /tmp/pg_standby.trigger.5432 /opt/postgres/archive/%f %p %r'
6.  postgres=# select pg_stop_backup();
7. Now I have made some changes to the master database  and I waited for 30 minutes 
8. I have stopped the master database
9. I have started the slave. But I did not find the changes I have done after I issued the command  elect pg_stop_backup();
10. The log files have shipped to archive folder
