Inconsistent Behavior for a Deleted Record

When deleting a record in PostgreSQL by running this for example:

delete from order_details where order_detail_id = 2;

The change record that reflects this:

"before":{ "order_detail_id":2, "order_id":0, "order_date":null, "quantity":null, "notes":null, "od_numeric":null, "od_decimal":null, "od_real":null, "od_double_precision":null, "od_bigserial":0, "od_text":null, "od_json":null}

In other connectors (tested MSSQL and DB2 for now), the before object represents the record before the deletion, while here the fields are set to null/0.
