main things to make it work are:

The patch which contains Windows implementation as well is attached with this mail. It contains changes related to following
1. waitpid
2. socketpair
3. fork-exec

The following is still left:
1. Error handling in all paths
2. During test, I found if i try to run with admin user, it throws error but psql doesn't comes out.
I will look into this issue. However as in previous mail discussion there is a decision pending whether in standalone mode
we need admin user behavior.
3. Will do some more test in Windows.

Currently I have prepared a patch on top of your changes, please let me know if that is okay.
Also, it will be better for me if you can tell me how I can further contribute.
