'dblink' Help

Hi,

I have Two databases names 'MyDb1' and 'MyDb2' in My
System.

I have installed Postgres 7.4 with dblink

What i need is, when ever a NEW record is inserted in
'MyDb1' , i want fire a Trigger or Rule to insert the
Same Record to MyDb2 database.

I am Using MAC OS 10.2

Anybody Got Idea how to do this?

Thanks

Some Sample Query Using "dblink" is:
select * from dblink('hostaddr=192.168.1.1
dbname=MyDb1 user=pgsql','select
username,password,usertype from users') as t1(username
varchar,password varchar,usertype varchar);
