In replying to me, you answered my original question (which was not answered)--I did not know that those start and stop shortcuts were in my start menu.
To respond to the rest of your post, the postgres database actually takes up a significant amount of resources for me. No, I do not think someone should have it running all the time if he or she uses it exactly once per day. Same goes for a virus scanner. If you cannot recall the last time you scanned a file for viruses, then you are probably better off not having your scanner on constantly. It's a waste, really. When friends and family ask me to clean their computers due to recent slowdowns, the number one culprit is always unused programs and services. Of those, a common offender is the major commercial virus protection programs. I kind of understand where you are coming from, but that was a bad example cause I am a huge, long-time critic of anti-virus software.
I'm sure if Josh is thinking about implementing an automatic shutoff, then he has thought about its implications and ways to avoid problems.
