hi, can postgres be run on a linux cluster, and if so what are the performance and other issues - checked archives, but the only info is over a year old
PG uses shared memory to communicate between backends. Even if your clustering technology can handle that, it's unlikely to be useful without exotic hardware. The main problem is bandwidth between the backends - they're not terribly independent, so you need a specialised backplane usually.
I think there is someone producing exotic hardware with a version called "clusgres" or similar. Not sure if anyone's seen one in the wild as it were.
