We also use Londiste 3 from Skytools. It seems londiste disables triggers via set session_replication_role = 'replica' and associated with the connection transactions do not fire triggers.

Hi, this comes a bit late, but it might be handy for future reference. You can set tgenabled='A' for the trigger with an update query and it will make the trigger fire, regardless of the session_replication_role. Specifics can be found in the docs: http://www.postgresql.org/docs/9.4/static/catalog-pg-trigger.html
