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".
