I am working with PostgreSQL 9.1.3 - I setup a master and standby -
Initiated replication and verified that it was occurring - Failed over
from master to standby and verified that the database could be updated
on the new master - I then configured the former standby as a master,
the former master as a standby and used the following command from the
new master to transfer data to the new standby:

rsync -av --exclude postgresql.conf --exclude pg_xlog
/var/lib/pgsql/9.1/data/* 192.7.143.213:/var/lib/pgsql/9.1/data (with
all previous data being removed by rm -rf *)

I then started the new standby first and after a short wait the new
master - The standby starts and initially has connect errors but after
the master is started the standby appears to start streaming replication
and then errors with a timeline error - On the new master all looks good
and the database can be accessed via psql.

Here is the content of my recovery.conf file:

standby_mode=on

primary_conninfo='host=192.7.143.111 port=5432 user=ruser
password=ruserpass'

trigger_file='/var/lib/pgsql/9.1/data/failover'

recovery_target_timeline = 'latest' (same effect when this line is
removed)
