In my experience, not really. We use SPARCs under Solaris 7 and,
now, 8. We haven't found any terribly obvious advantages with the
system compiled as a 64 bit app, but we _did_ find problems with the
64 bit libraries combined with gcc. As a result of that and
pressures to get working on some other things, we stopped testing
Postgres as a 64 bit app on Solaris. We haven't done any work on
Solaris 8 with it, and that system is a little more mature in the
64-bit-support department, so when I have a chance do to more
investigation, I will.

I think the problem with int8s in a lot of cases has more to do with
typer coercion. So at least in systems < 7.4, I'm not sure you'll
see a big win, unless you make sure to cast everything correctly.
