How to update Remote DB using trigger?

Hi,

I am using two Postgre databases in my application. Both are in different in
machine.
My requirement is that when one database(primary) gets updated then the
another database(secondary) should also get updated with the same
information updated in primary database.
I think trigger will help in this.
But I am not sure about the connection to remote database from stored
procedure.
Can anyone help me?

Regards,
Natrayan.
