What problems do you see with Slony + Linux HA combo there? I think a Slony
failover can do the same and promote a slave node to master in case of a
master node failure, and then you can actually do the load balancing by
using the slave nodes in the system.
Please let me know on any updates for OpenSSI if you get a chance to try
that out

I have a simillar problem, such that the HA aspect involves multiple data
centers. I can deploy multiple systems within a single data center and
achieve HA within that data center using the techniques discussed in this
thread. What I have not been able to come up with a good semi-general
purpose solution to is cross-data-center HA. As a result we are using very
application specific techniques to try to address this, but the longer
term maintenance we suspect will be high. How do others deal with this
problem?
