AFAICS you haven't done anything particularly strange (although your
habit of rebooting every time you turn around seems pretty odd to an
old Unix hand ;-) ... that's really not necessary, nor is stopping and
restarting Postgres a useful exercise in my opinion).
I frankly suspect hardware problems. You should try some testing with
memtest86 and badblocks to see if they turn up anything in the way of
flaky RAM or disk drive respectively.
