Подскажите почему не отрабатывает скрипт? Ситуация такая: есть БД Постгриса, в которую парсятся логи Сквида по алгоритму - подключаемся к БД-Сбрасываем индексы-Вставляем данные в таблицу учитывающую ВСЕ запросы пользователей - Очищаем таблицу где собраны суммарные данные за день по юзерам - суммируем записи из подробной таблицы и вписываем эти данные в общую таблицу - дальше обслуживание БД (создание индексов, дефрагментация и пр.) Индексы то он сбрасывает и данные в подробную таблицу вписываются, а вот дальше никак. И логов то нет, чтобы посмотреть что не так (правда когда скрипт вручную запускаю с консоли видно как он выдает ошибки типа "use of uninitialized value in concatenation (.)"
Вот текст скрипта:
