Error

ERF42-7495 [Foreman::Exception]: Cannot find user foreman_admin when switching context
If you feel this is an error with Foreman itself, please open a new issue with Foreman ticketing system, You would probably need to attach the Full trace and relevant log entries.



Expected results:
-----------------------------------------
The users are not removed the database, satellite is upgraded, and is fully functional. 



Adding the users to satellite's database fixes the issues:
-----------------------------------------
# su - postgres 

# psql foreman

foreman=# insert into users (login, firstname, lastname, admin, created_at, updated_at) values ('foreman_admin', 'Anonymous', 'Admin', False, '2014-08-12 19:12:03.910693', '2014-08-12 19:12:03.910693');

foreman=# insert into users (login, firstname, lastname, admin, created_at, updated_at) values ('foreman_api_admin', 'API', 'Admin', False, '2014-08-12 19:12:03.910693', '2014-08-12 19:12:03.910693');
