Здравствуйте! При выполнении любого запроса в SQL Executor на демостенде(тестдрайв) версии 7.16.0.4461 выдаётся ошибка.

Например делаю такой запрос:

select * from Contact

Сама ошибка такая:

Npgsql.PostgresException (0x80004005): 42P01: relation "contact" does not exist

В чём может быть проблема?
