Thread: Help on creating a High Availability PostgreSQL solution?
We are looking to create a two-machine high-availability configuration for PostgreSQL. We have been pursuing using something like rserv, but this appears to be more of a slave sync tool. Actually, this is also important to us (as we expect we will need to scale to lots of readers doing queries on the database (we are running datamart of website performance metrics). But, rserv (and eRServer, its commercial cousin) dont seem to have a hot-standby capability at the moment. I have looked through some of the PostgreSQL archives and I've seen articles about other approaches, but I mostly see replication engines (which are a good thing, but not what I am hunting for). I saw one posting that suggested using a clustered filesystem; is this an option? Has anyone done postgreSQL on a replicating/clustered file system with decent performance? Any and all ideas are welcome. Thanks in advance, Charlie -- Charles H.

We are selling Lifekeeper (a hot-standby cluster software) + PostgreSQL adapter software for Lifekeeper + support combo package called "PostgreSQL HA package" in Japan. This requires an expensive shared disk hardware though. -- Tatsuo Ishii
