If you make a new constraint in 7.3, the dump from a 7.3 server should use
ALTER TABLE to build the constraint. That will check the data. If you've
imported a constraint from an earlier version it doesn't have the new
constraint info and will still just dump them as triggers. You can make
the constraint information for those triggers (I think someone made a
script to do that) but I'm not 100% sure what's involved.
