Last time this problem came up, in August, you dismissed it somewhat
rudely. So perhaps the lack of reports is due more to perception than any
other thing.

What's the corner case exactly? 8.3 dumps it correctly, but that's not
really much of a consolation because I need to restore _this_ dump, not some
other one. It was necessary for me to recreate all the sequences and set
the curvals manually.

Can't the fix be backported to 8.1?
