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)
