postgresql 8.0 on windows 2003 server

Hello everyone.  Thanks for the answers earlier about the new 8.0 version.

We have a client who is thinking about putting postgresql 8.0 on Windows
2003 Server, but he is concerned because this is the first version to
run natively on windows.  Are there any issues with 8.0 on Windows?

Also, with Linux it was possible to improve performance by increasing
the amount of shared memory in /etc/shmmax
(http://www.phpbuilder.com/columns/smith20010821.php3).  Does this need
to be done in Windows?

Thanks!
