Trzeba przekonwertować scalanie Oracle na zapytanie do PostgreSQL

Możesz użyć INSERT ON CONFLICT () zamiast tego:

insert into feepay.TRPT_W2_REPORTS (ACCOUNT, URN, LAST_NAME, FIRST_NAME, ISENTITY, DOB, ADDRESS, LAST_UPDATE, STATUS)
WITH RWS AS (
  SELECT PROG.BINCLIENT, TRPT.PUT_DIRECTORY
  FROM  feepay.program2 PROG
    INNER JOIN  feepay.TRPT_W2_PROGRAMS TRPT
            ON (PROG.BINCLIENT = TRPT.BINCLIENT OR PROG.ISSUER_ID = TRPT.ISSUER_ID)
)
SELECT TCI.CUSTOMERNAME,
       TC.CUSTOMER_ID,
       TC.LAST_NAME,
       TC.FIRST_NAME,
       'Y'
       TC.DOB,
       TCA.ADDRESS, 
       now(), 
       'i'
FROM feepay.TAU_CARDNUMBERS TCN
  INNER JOIN feepay.TAU_CUSTOMER_CARDNUMBER TCCN ON (TCN.CARDNUMBER_ID = TCCN.CARDNUMBER_ID)
  INNER JOIN feepay.TBLCUSTOMERS TC ON (TCCN.CUSTOMER_ID = TC.CUSTOMER_ID)
  LEFT JOIN feepay.tau_customeraddress TCA ON (TC.CUSTOMER_ID = TCA.CUSTOMER_ID)
  INNER JOIN feepay.TAU_ISSUER TI ON (TI.ISSUER_ID = TCN.ISSUER_ID)
  INNER JOIN feepay.TBLCUSTOMERS TCI ON (TCI.CUSTOMER_ID = TI.CUSTOMER_ID)
  LEFT JOIN feepay.TRPT_W2_REPORTS TRPT ON (TRPT.URN = TC.CUSTOMER_ID)
WHERE BINCLIENT IN (SELECT BINCLIENT FROM RWS)
  AND TC.CUSTOMERNAME NOT IN ('freepay card','svds card')) TRPT2
ON CONFLICT (URN)
DO UPDATE SET
  ACCOUNT = excluded.ACCOUNT,
  LAST_NAME = excluded.LAST_NAME,
  FIRST_NAME = excluded.FIRST_NAME,
  DOB = excluded.DOB,
  ADDRESS = excluded.ADDRESS,
  LAST_UPDATE = now(),
  STATUS = 'u' /* uPDATED */

Musisz sprawdzić, czy kolumny na liście SELECT odpowiadają kolumnom wymienionym na liście kolumn INSERT.
