Once I had such experience on 9.0.x and here is the note I made for myself:
To switch a replica to read from the new master after switching it
over add the following instruction in the recovery.conf on the
replica.
recovery_target_timeline = 'latest'
Then stop the service, resync the pg_xlog directory on the replica and
start it. Note that the old master must be stopped before switching
the new one over. It will prevent replicas from timeline divergence.
ps. I tried to adjust the x..xx.history file to avoid re-syncing
pg_xlog but without any success.
pps. BTW I still wonder if it is possible to avoid the re-syncing. May
be it could be done by setting restore_command?
