Hi All
The following problem is what I had posted before.
I have received comments from PostgreSQL-hackers that
this problem have a possibility to exploit the vulnerability.
http://postgresql.1045698.n5.nabble.com/PostgreSQL-Service-on-Windows-does-not-start-quot-is-not-a-valid-Win32-application-quot-td5776048.html
So could anyone confirm?

Naoya
