Whatever technical problems there are, we can debate on and
on if it's worth working around them in PostgreSQL or fixing
them in CygWIN or whatever.

The main problem will remain. That using PostgreSQL under
CygWIN requires some UNIX know how. So a pure Windows
user/shop needs UNIX knowledge to run our "Windows port" of
PostgreSQL? Interesting definition of "port".
