Just my 2 cents, and not looking to the technical aspects: setting up PSQL is the weakest point of PSQL as we have experienced ourself, once it is running it is great. I can imagine that a lot of people of stops after their first trials after they have experienced the troubles and performance of a standard set up. This is ofcourse a lost user forever. So anything that could be done to get an easier and BETTER setup would strongly enhance PSQL. My 2 cents.
