Настройка непрерывного архивирования WAL
Для выполнения копирования в режиме PAGE, восстановления на момент времени, создания резервных копий с использованием режима доставки WAL ARCHIVE и восстановления инкрементальной копии после смены линии времени, должно осуществляться непрерывное архивирование WAL. Чтобы настроить непрерывное архивирование, выполните следующие действия:
Означает ли это, что бэкапы PAGE при выполнении требований из этого раздела документации должны без проблем выполняться после смены Timeline?
В нашем случае это не соблюдается
