We can't just install any softwares without Goverment's approval. Also, they might ask Oracle/mysql/sql can run batch script, why not Postgres? I wonder myself and just realize today from this email.
PostreSQL isn’t the issue here, you are. To the extent that others attempting to help you over email are insufficient is a failing driven mainly by the medium of choice probably being an inefficient medium for the student. What you want to do is possible but it requires understanding multiple applications. You are better off getting closer to your goal by reading books and articles about those applications and then asking better questions. Or at minimum being more detailed in stating your goal and requirements.
