BUG #11501: PostgreSQL for Windows (installer) cannot be installed by screen reader users (blind computer users)

The following bug has been logged on the website:

PostgreSQL version: 9.3.5
Operating system: MS Windows
Description:

The PostgreSQL installer for Windows that can be downloaded from:
http://www.postgresql.org/download/windows/

offers a totally inaccessible interface for screen readers so it can't be
installed by blind programmers.

I don't know what graphical classes it uses but it looks like Java Swing
(from the perspective of a blind).

I checked in Java/jre7/lib/accessibility.properties file and the following
line is uncommented, so Java Swing classes should be accessible with Java
Access Bridge:

assistive_technologies=com.sun.java.accessibility.AccessBridge

So the installer probably uses another inaccessible graphical interface, or
same as bad, uses its own Java distribution.

Can this be solved, or at least provide an easy solution to install
PostgreSQL by using the zip archive?
(Which implies setting the PostgreSQL server Windows service, setting the
necessary paths that may be needed in PATH env variable etc).

Thanks.
