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 state: 42601
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.

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

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

Thanks&Regards,
venkat.
