I'm embarrassed to say it is 8.2.3 :( I'm not sure why they haven't
upgraded our production servers to the latest 8.2 yet. It's running on
Windows Server 2003, and it looks like there is plenty of disk space.
I googled this and found someone reported defect 2461 for this, some
time ago, but I'm not clear how to check the status of that bug. I
subscribed to pgsql-bugs so I can ask there as well.

I also checked the logs from yesterday and I don't see anything that was
logged while the pg_dump was running.
