SQL Server like mysql, is very 'noob friendly'...it doesn't require a
lot of configuration to be quick is forgiving of lousy access
strategies to the database (these are good things btw).

PostgreSQL 8.0b was still using old style win32 fsync which maps to
flushfilebuffers()...this is an an ultra conservative way of flushing
ot disk so this is not apples to apples comparison. That said, SQL
Server will be very hard to beat with write performance on windows
because it is very tuned to the win32 api and has very efficient disk
access. In the mean time for a fairer test you have to turn fsync off
in postgresql.conf and you definately want to be running pg 8.1 which
has tons of improvements for win32 and a more efficient
syncer...although in windows for production database I would highly
suggest targeting a caching raid controller.

I am right now in the development planning phase of a PostgreSQL
databse which has to scale well into the terabyte range. I can tell
you without hesitation that the database can handle it and deserves
the reputation of a workhorse that it has. Administrating pg is a bit
harder to get into but well help you understand what a database is
really all about and how to make your data access elegant and
efficient.
