function runs on Windows not on solaris

Hi

I am using PostgreSQL 7.3.2 on Solaris 8 machine.

I have written following procedure for Windows ( testing purpose ) and solaris ( production ). It works well on windows but gives following error on solaris. Can anyone help me to find out what is the problem ?

CREATE OR REPLACE FUNCTION p_MapLicKeyToAccount(VARCHAR,VARCHAR) RETURNS INT4 AS '
DECLARE
licKey ALIAS FOR $1;
accountId ALIAS FOR $2;
checkLicKey VARCHAR DEFAULT NULL;
checkAcctId VARCHAR DEFAULT NULL;
BEGIN
IF accountId ISNULL THEN
RETURN 1;
ELSE
SELECT INTO checkLicKey license_key FROM db_license_tab WHERE license_key=licKey;

IF checkLicKey ISNULL THEN
RAISE NOTICE ''License Key % does not exists'',licKey;
RETURN 2;
END IF;

SELECT INTO checkAcctId account_id FROM db_license_tab WHERE license_key=licKey;
IF checkAcctId NOTNULL THEN
RAISE NOTICE ''License Key % already used'',licKey;
RETURN 3;
END IF;

checkAcctId = NULL;

SELECT INTO checkAcctId account_id FROM db_acctmaster_tab WHERE account_id=accountId;

IF checkAcctId NOTNULL THEN
RAISE NOTICE ''Account id % already exists'',accountId;
RETURN 4;
END IF;
UPDATE db_license_tab SET account_id=accountId,license_anniversarydate=current_date(),license_status=1 WHERE license_key=licKey;
END IF;
RETURN 0;
END
' LANGUAGE 'plpgsql';

Error:

MYDB# select p_MapLicKeyToAccount('1B5D892169812C6F','testsuraj@max.com');
WARNING: Error occurred while executing PL/pgSQL function p_maplickeytoaccount
WARNING: line 36 at SQL statement

Thanks & Regards,
