  Как полностью удалить программу?
  Делал по этому руководству:

  Руководство по деинсталляции PostgreSQL
  Если при создании базы данных программа не может подсоединиться к «Localhost», установлена старая версия PostgreSQL (8.3, например) или возникает какая-либо другая проблема, лучшим решением часто будет полное удаление текущей версии программы PostgreSQL из системы с последующей переустановкой заново вместе с Elephant’ом.

  Пожалуйста, постарайтесь на 100% придерживаться данного руководства по деинсталляции для обеих операционных систем (Vista, XP)!

  Для операционной системы Vista:

  Условия: убедитесь в том, что функции вида папок позволяют вам видеть скрытые файлы (см. окончание руководства для Vista), Postgres установлена в C:/Program Files/Postgres, и учётная запись пользователя называется «postgres».

  1) Пуск -> Панель управления -> Программы и компоненты -> Postgres / клик правой кнопкой мыши -> Удалить/изменить

  2) Нажмите «Пуск», в поле для поиска введите «cmd». Поиск должен вывести один результат, кликните по нему правой кнопкой мыши, выберите «Запуск от имени администратора»

  В диалоговом окне DOS введите:

  «net user postgres /del»

  3) В папке C:/Documents and Settings полностью удалите папку Postgres

  4) Полностью удалите папку C:/Program File/Postgres

  Очистите корзину, перезагрузите компьютер, готово.

  Как сделать скрытые файлы и папки видимыми:

  Зайдите в Пуск -> Панель управления > «Свойства папки». Кликните по вкладке «Вид».

  Уберите галочку с опций «Скрывать защищённые системные файлы» и «Скрывать расширения для зарегистрированных типов файлов».

  Поставьте галочку рядом с опцией «Показывать скрытые файлы и папки»

  Но у меня В папке C:/Documents and Settings полностью удалите папку Postgres
  Нет такой папки.

  В итоге не могу полностью удалить старую программу что бы поставить Холдем Менеджер
