@Dave: In the reply you have mentioned ablout the code, but I am not able to get pgadmin code by now. Would you please give me the link from where can I get the code.
I have to point out though, that asking a question to which you could find the answer by looking at the project website for 30 seconds (or using Google) doesn't give a good early impression.
Also I had a question in mind:
Is the acceptance of a GSoC application is affected if you submit your application your application in the beginning or at the end?
No. Once submitted though, I would recommend responding to any questions raised by the mentoring team in a timely fashion.
