John,
Basically, what I'm searching for is something that relay sql to others
postgres instances.
The main goal is to have this proxy balancing, and better if it can
figure out when a postgres server is down. It would give me better
performance and will help mitigating the single point of failure, as I
can use HA for the proxy only.
The final idea is big, but I wanted to know what are the tools
available, end then start with it.
Cheers
Martin
