I was mistaken. The FK is on PS_CUST_ID on CU instead of CUSTOMER_ID
So the FK is CO.CUSTOMER_ID references CUSTOMER.PS_CUST_ID.
The CUSTOMER_ID in CU is not REFERENCED.

There is no reason to do the join because the RI tells us that the CU row HAS
to be there. You are not pulling any data from CU and not filtering on data
from CU. Right?
