Minor usability/debuggability suggestion...
RI violation error messages in 7.0.0 do not appear to identify the
offending value.
Example:
ERROR: fk_employee_currency referential integrity violation - key
referenced from employee not found in currency
Easier to debug would be:
ERROR: fk_employee_currency referential integrity violation - key '27'
referenced from employee not found in currency
