I wonder if it wouldn't be better to have something like the machinery
around ErrorContextCallback to fill in the constraint details. You'd then
only need to modify the places which initiate constraint checks, instead
of every single ereport() in the constraint implementations.
Just a wild idea, though - I haven't check whether this is actually
feasible or no.
