I have a production PostGres v8.2 database on luinx and a test PostGres V9.0 database on a test linux server
I am going to do migration but do not want to do that before making sure the performance of the new test Postgres 9.0 database performance is as good as the current production Postgres 8.2
My question is:
Is there a script that I can run on Postgres V8.2 and PostGres 9.0 that allows me test performance and make comparisons

(I recommend it even for non-PostgreSQL admins because it goes so in-depth
on Linux tuning) so whether you get it for free or not, it's worth the time it takes
to read and absorb the info.
I've never run PostgreSQL virtualized, but I can say that if it's anything like
running SQL Server virtualized, it's not a terribly good idea.
