that can probably be done (using C for instance) , but do you really want the
penalty of every insert waiting for a connection to be established to the
remote server?

some other systems use the trigger to insert the nes column into holding a table
and trigger a notify,

then a separate application waiting for the notify retreives the row
and inserts it onto the remote server.
