Has anyone got experience with data quality checking, validation and reporting within PostgreSQL?

How best to use PostgreSQL CHECK Constraint for data quality checking, validation and reporting?

Can we report on errors in a detailed and specific way? For instance, can we produce report on specific issues of erroneous cells in which row and etc.?

Regards,

David
