In my case my primary issue was getting an elastic-ip to disassociate from one instance and reassociate to the new primary. My use-case was to build a HA pair of HA-Proxy servers, thus the need to float a VIP. If I had a real physical datacenter i'd just have used CARP, but thats not really workable in AWS or public could environments. I'd be interested in hearing about what specific issues you are running into, while I agree the upstream community is pretty linux-centric I was able to it working pretty well. Another option that might be worth exploring is using ha-proxy itself to serve a VIP of our psql db endpoint, I've found it to work pretty well for load balancing various TCP services and the REST api is super handy as well. -pete
