FWIW, I'm testing on ZFS now. But it's not stable yet. People are welcome
to join the Solaris 11 beta program.
In the near term, there are fixes to be made both in PostgreSQL
configuration and in Solaris configuration. Also, some of the work being
done for 8.2 ... the external sort work done by Simon and sponsored by
GreenPlum, and the internal sort work which Jonah and others are doing ...
will improve things on Solaris as our sort issues hit Solaris harder than
other OSes.
Expect lots more info on performance config for Solaris from me & Robert in
the next few weeks.
