I don't think it will often be the case that the stats collector will miss updating the information. I am not feeling comfortable storing error information in system catalogs. We have some other views which capture somewhat similar conflict information (pg_stat_database_conflicts) or failed transactions information. So, I thought here we are extending the similar concept by storing some additional information about errors. -- With Regards, Amit Kapila.
