[ raised eyebrow... ] I think your machine is flakier than you believe.
This error is particularly damning, but the general pattern of weird
failures all over the place seems to me to fit the idea of hardware
problems much better than any other explanation. FC6 and PG 8.2.3 are
both pretty darn stable for most people, so there's *something* wrong
with your installation, and unstable hardware is the first thing that
comes to mind.
