Thanks for responding. I am using postgresql-9.4.4-3 version to install. However I am getting the same issue with postgresql-9.3.9-3 version as well. Kindly suggest, what needs to be done.
I am unable to install Postgresql on window 2003. I have already installed previously. As, I forgot the password, I have uninstalled and trying to install again.
I got error as " The database cluster initialization failed ".
The solution to this problem I got as "During the installation, you are asked to choose a location to store the postgres data. The default location is C:\Program Files\Postgres\data. Choosing a location outside of the Program Files directory (e.g. C:\Postgres Data) can often overcome the problem described above. " I got the solution from http://www.maplesoft.com/support/faqs/detail.aspx?sid=33315
After doing the above steps, the setup is stuck at the final stage. It is just showing as "Installing the database cluster (this make take few minutes)".
