PokerTracker

Does anybody know is it possible to install Postgres Plus® Advanced Server 8.3 R2 instead of normal PostgreSQL that came with PokerTracker 3?

And does anybody know is this better than the regular one? The thing is that I have Core I7 965 and 8GB 2133mhz RAM, So I would like the
PostgreSQL server optimized for my computer. It could take 7gb of mem and 95% CPU power, but now it takes so little of ram and cpu but
the harddrives are rolling 100%.

PostgreSQL is very hard drive intensive - retrieving the data is most of what actually ends up taking time at this point.

Unfortunately I don't have any knowledge of the Postgres Plus Advanced Server, so I don't know if it will be any better personally.
