Let me echo that, because it's extremely important: when I was in charge of hiring people to work on our databases, I was very concerned not to get the sort of people who felt that the system was "the sysadmin's problem". You _cannot_ treat the operating system as not your problem when addressing performance questions in PostgreSQL. This is a very unfamiliar situation to most Oracle and some DB2 administrators, in my experience.
