[mod] make ViolatedConstraint actually display useful information Move from: (Pdb++) raise some_exception *** ViolatedConstraint: To: (Pdb++) raise some_exception *** ViolatedConstraint: constraint 'cstr56c2ab4b3154f21d08b067742ce5bd9d' is being violated by the query 'ALTER TABLE cw_Bibliography ADD CONSTRAINT cstr56c2ab4b3154f21d08b067742ce5bd9d CHECK(cw_item_type IN ('journalArticle', 'note', 'book', 'thesis', 'film', 'web page', 'manuscrit', 'tapuscrit'))'. You can run the inverted constraint on the database to list the problematic rows. And save hours of debugging to actually understand what is going on.
