OracleマージをPostgreSQLへのクエリに変換する必要があります

INSERT ON CONFLICT ()を使用できます 代わりに：

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 */

SELECTリストの列がINSERT列リストにリストされている列と一致するかどうかを確認する必要があります。
