Я пытаюсь клонировать базу данных из одного postgres в другой. Я использую старую версию postgres 8.1.4, новая база данных находится внутри docker контейнера, работающего под управлением Ubuntu.
Мне нужно будет скопировать полную базу данных, но для простоты сейчас я показываю ошибку в одной таблице. На текущем заполненном сервере я делаю:
pg_dump -U postgres -d cnx -t freq1_data -F c > /data/misc/luca/freq1_data.dump, чтобы сбросить таблицу.
затем я создаю контейнер со следующим dockerfile

postgres@c1ee3cfe5dbf:/$ /usr/local/pgsql/bin/pg_restore -U postgres -d cnx /cnx_data/freq1_data.dump
, эта последняя команда возвращает большое количество ошибок:

Я чувствую, что что-то упустил. Как определение схемы, но я не могу понять, что делать.
РЕДАКТИРОВАТЬ 1: После запуска: create schema smdata
Я получаю сообщение об ошибке:

Похоже, он не скопировал схему из старого БД.
