First, it is not *my* license. Second, IANAL (again). Third, you are
not being very clear (again).
Nevertheless, if you are referring to the Cygwin license:
http://cygwin.com/licensing.html
then the following is the essence:
If you distribute binaries linked against the Cygwin DLL, then you
must also distribute (or at least make available) the corresponding
source to satisfy the GPL.
Hence, if your code does not link against the Cygwin DLL, then you do
not need to distribute its source. However, you do need to distribute
the source for PostgreSQL, the Cygwin DLL, and any other (e.g., sh)
Cygwin binary that you distribute.

Add to be explicit: If your code does link against the Cygwin DLL, then
you do need to distribute its source.

It is possible to write PostgreSQL client applications than don't use
the Cygwin DLL and don't need to be open source. The libpg client
library complies and runs natively under Windows. A Windows application
can be linked against that library and not need to use Cygwin. This is
done with the Perl DBD::Pg module.
