Well, OSDL has run tests on PostgreSQL as recently as 20050908 but the
host with the results isn't responding to me, so no idea what the tests
were. Also, they use various tests involving PostgreSQL to test the
scalability of the Linux kernel, so you can see how postgres runs with
various different kernel patches.

Enter "postgresql" in the software field, or select one of the pgsql
tests. Maybe someone else will have more luck than me getting the
results...
Have a nice day,
