As an equally unscientific data point, on my box, a typical desktop box
(actually a netbook, slow CPU, but beefed up to 2GB RAM), I have 5
PostgreSQL processes running, which take away about 1.2 MB (resident) --
not each one, but together!. As a contrast, there is *one* mysql daemon
(don't ask!), taking away 17 MB. The worst offenders are, by far, the
eye-candy thingies, as one has become accustomed to expect :-(
What I wanted to say is that the PostgreSQL processes are unusually
light-weight by modern standards.
