The whole system freezes, not only Postgres? In that case I don't think
you need to guess very hard: you've got a hardware problem. Well, maybe
it could be a kernel bug, but I'd bet hardware. In any case, Postgres
is an unprivileged user process: it can *not* lock up the rest of the
system. It could tickle a kernel bug that results in a lockup, but that
doesn't make it Postgres' fault.
