I am looking for Failover and Loadbalancing in postgresql. my choice is very likely to be pgpool. but i have concerns regarding it beeing a SPOF. so i found pgpool-HA. but nowhere is a description of what this actually does. I would like to keep all my VMs the same (not have a dedicated DB loadbalancer) So there would be a pgpool server on every database server knowing about all other databases. my goal would be to be able to takl to any of the pgpool instances and get the same result. the question is will pgpool-HA keep the information about what servers are available/disconnected synchronised over all pgpool instances. or is it just a hot-standby solution where the new pgpool server takes the place of the old one if it fails.
tldr; is a active:active configuration for pgpool instances possibel with pgpool-HA?
