If you search for OpenSSI Postgres, you hit this link: http://wiki.openssi.org/go/PostgreSQL_on_OpenSSI_enabled_Knoppix I have done this setup and small test on it about an year ago. The performance was horrible. I cannot say for sure, but I think, as OpenSSI FAQ mentions it, it's because of the way Postgres works with shared memory. I hope you find that article useful in starting your own experiment. Lets hope there's some improvement since last year. Do let us all know the results.
