single task postgresql

Having frustrated with performance on Windows box I'm wondering if it's
possible to get postgresql optimized for working without shared memory,
say in single-task mode. It looks like it's shared memory emulation on disk
(by cygipc daemon) is responsible for performance degradation.
In our project we have to use Windows for desktop application and it's
single task, so we don't need shared memory. In principle, it's possible
to hack cygipc, so it wouldn't emulate shared memory and address calls
to normal memory, but I'm wondering if it's possible from postgres side.

Regards,
Oleg
