ERROR: syntax error at or near "NEW"

HI,

I am having a problem with connection of two databases in different
systems.Let me explain clearly.

I have one postgres 8.4 server running in my system and another postgres
server running in
my friend system

My requirement is whenever ,I do some insertions in a table in my postgres
server the same things should be replicated
in another postgres server.

These are the steps I followed
----------------------------------------------------------------------------------------------------
1.Creation of table in a database named "testA" in one system say "sys1"

CREATE TABLE emp
(
empname text NOT NULL,
salary integer
);

2.Creation of table in a database named "testB" in another system say
"sys2"

CREATE TABLE emp
(
empname text NOT NULL,
salary integer
);

3.Creation of a Function and Trigger in database "testA" in "sys1"

CREATE OR REPLACE FUNCTION process_emp_audit() RETURNS TRIGGER AS
$emp_audit$
BEGIN
IF (TG_OP = 'INSERT') THEN
SELECT * FROM dblink_exec('hostname=sys2ip dbname=testB
user=postgres password=postgres','INSERT INTO emp
NEW.*');
RETURN NEW;
END IF;
RETURN NULL;
END;
$emp_audit$ LANGUAGE plpgsql;

CREATE TRIGGER emp_audit
BEFORE INSERT ON emp
FOR EACH ROW EXECUTE PROCEDURE process_emp_audit();

4.The error I got is

ERROR: syntax error at or near "NEW"
CONTEXT: Error occurred on dblink connection named "unnamed": could not
execute command.
SQL statement "SELECT * FROM dblink_exec('dbname=test9','INSERT INTO emp
NEW.*')"
PL/pgSQL function "process_emp_audit" line 3 at SQL statement

********** Error **********

ERROR: syntax error at or near "NEW"

SQL statement "SELECT * FROM dblink_exec('dbname=test9','INSERT INTO emp
NEW.*')"
PL/pgSQL function "process_emp_audit" line 3 at SQL statement.

---------------------------------------------------------------------------------------------------------------------------

So,I request you for any kind of solution for this problem.

Thanks&Regards,
