High Availability with hot-standby and auto-failover in postgresql -


i asked implement high availability , auto-failover in postgresql , have been searching internet on find right architecture that.

i have tried in 2 architectures:

  1. redhat cluster
  2. ucarp

both ways came out pretty bad when i've meet bugs on ucarp restarting master-master after several reboots , redhat cluster fails manage postgresql service.

i ask if has ever succeeded implement such architecture , explain me how or refer me tutorial works.

the components have are: postgresql @ latest version (9.4), rhel 6.6 , higher, on virtual machines.

thanks in advance, aviel buskila.
