Sure, with PostgreSQL I can do my own research. I might even have skills to do it myself. But now I have to explain my choices all the way up the ladder.
Am I going to use an OSS accounting system with no sales people? With no support people? Or am I gonna pay $99 a year or whatever for QuickBooks?
