This is akin to saying that an application written to use MySQL will
never perform well on PostgreSQL. It depends on *how* the code is
written. If your SQL is tuned to one database, it will likely have
performance issues on other databases. Likewise, a process-based server
will perform poorly on Windows, while a threaded server will not. This
is an implimentation choice. There's no reason why PostgreSQL on windows
*has* to be process based (though of course there would be serious
technical issues with changing it).
Of course, by simply hand waving and saying "it can never be better", it
never will be better.
