Agreed.  I had that same problem with upgrading to 7.2.  My solution was 
to install 7.1.3 on another box, load, massage, dump.  Next time, I'll 
keep the old version around a bit longer.

I think that is an eloquent solution.

But if the user has already dumped and flushed his old installation,
he's still in need of a time machine.

Hmm, maybe what we need is a tool that can be applied during load.
Essentially, alter incoming constraint names as needed to make them
unique.  We could have this enabled by a SET switch...
