After I freed up space on the pg_xlog partition and restarted, it took
some time to replay all of the log (15-20 minutes) and everything
recovered with no data corruption! However, the theory about the data
partition filling up first didn't happen in my case. The data partition
was (and still is) less than 50% utilized. My pg_xlog files typically
run around 400MB, but with the long running update filled up the entire
10GB partition. (which is now a 70 GB partition)
So, I'm still not sure what caused the problem. When I get back to work
(or maybe sooner), I'll take a look in the PG logs and post anything
that looks suspicious here. Thanks for all of your comments and
suggestions. Even though I haven't figured out the root of the problem
yet, they've been very informative.
