I don´t know how to create a patch, maybe someday, but for now I´m just sending this little problem if somebody can solve it.
In a multi schema environment where several tables has same structure is a little bit hard to know which one already has that primary key. On log I see now on replica server. Message:duplicate key value violates unique constraint "pkcustomer" Detail: Key (customer_id)=(530540) already exists. So, I know what table is but I don´t know what schema it belongs. Thanks Marcos
