* Benchmarking PG

Hi to all.
I'd like to benchmark PG. I'd like to compare sorting performances (time spent, #of disk accesses, # of run produced etc) of the present Replacement Selection (external sorting) algorithm and of a refinement I'm going to implement.
I'm new on PG, I just had the idea of how to possibly get better that algorithm and choosed to test it on PG since it's an open-source DBMS.
I've been searching the web for a benchmark. I suppose TPC-H and Wisconsin could fit, but had problems when trying to use them.
Any suggestion on a "good benchmark"?
Any tutorial on how to use them?
Thanks for your time.
Regards.
Manolo.

Well, there's pgbench. http://www.postgresql.org/docs/8.3/static/pgbench.html

Hi Josh!
Thanks for your reply.
Actually I forgot to mention PGBench, sorry. But I also forgot to mention I'm looking for an "impartial"... I mean "outer" tool to test PG.
Any suggestion, please?
Regards.

If you want to compare sorting performance in particular, running a big
query that needs a big sort will be much more useful than a generic DBMS
benchmark like TPC-H.
