Hmph. I still can't reproduce this here, which seems to mean one of
three things:
1. We fixed this since 8.3.15 (still doesn't seem likely).
2. It's specific to Windows.
3. It's specific to the pg_dump build you are using.
I wonder whether anyone else can get this to happen on the strength of
David's description?
