I think you're asking the wrong question. I think what you want is
"what performence does postgresql get on benchmark X with hardware Y".
I don't beleive you actually get performence numbers for other
databases without a whole list of constraining factors. You need to be
a lot more specific about what you want to know. You can find
benchmarks on the web, but really you need to evaluate whether they're
testing what you want to know.
But ok, here's a number: I can insert 100,000 rows per second on this
machine next to me. How does that help you? It doesn't: you don't know
the machine or the software or how it's configured or what I'm
inserting. You don't even know if this machine exists (hint: it
doesn't).
Also, insert/update speeds are useless measurements. If all you want is
that, please look at berkley DB. PostgreSQL is a SQL compliant
database.
Anyway, here are some sites to help you formulate your question better:

Hope this helps,
