PostgreSQL version: 9.2.2
Operating system:   Windows 7 x64
Description:        =


When i try to install postgresql-9.2.2-1-windows-x64.exe, it ask aboute DB
files path.
I have chosen d:\Server\DB\
then installer runs but file:
"
@ECHO OFF
icacls D:\ /grant "NT AUTHORITY\NetworkService":(NP)(RX) >
"C:\Temp\rad9B244.tmp" 2>&1
EXIT /B %ERRORLEVEL%
"
It is incorrect. I believe that cacls should be run only on specified path
(d:\Server\DB\).
Besides this path have full access for Everyone and Administrators.
