ApplicationName works for me - "Server=localhost;Port=5432;User Id=***;Password=***;Database=***;ApplicationName=test".

In case there are people who searched for answer to this question, here is the solution: application_name=MyApp will not work for npgsql version 2.2.4.3 (Latest Released 2015-02-05) Change application_name to ApplicationName=MyApp
