尝试克隆postgres数据库（pg_dump，pg_restore）时出错

Question

我正在尝试将数据库从一个postgres克隆到另一个。我正在使用旧版本的Postgres 8.1.4，新数据库位于运行ubuntu的docker容器中。

我需要复制完整的数据库，但是为了简单起见，现在在单个表上显示错误。在当前填充的服务器上，执行：

pg_dump -U postgres -d cnx -t freq1_data -F c > /data/misc/luca/freq1_data.dump以转储表。

然后我使用以下dockerfile创建容器

FROM ubuntu:18.04
RUN apt-get update -y
RUN apt-get install python3.8 -y
RUN apt-get install python3.8-venv -y
RUN apt-get install python3.8-distutils -y
RUN apt-get install python3.8-venv python3.8-dev -y

RUN apt-get install gcc -y

RUN mkdir adam
ADD /adam/ /adam/
RUN mkdir /cnx_data/


RUN python3.8 -m venv adam_env
RUN /bin/bash -c "source /adam_env/bin/activate"
RUN ./adam_env/bin/pip install -r /adam/build/requirements.txt
RUN ./adam_env/bin/pip install -e /adam/src/adam/



RUN apt-get install build-essential -y
RUN apt-get install wget -y
RUN apt-get install -y build-essential libreadline-dev zlib1g-dev flex bison libxml2-dev libxslt-dev libssl-dev
RUN apt-get install -y clang

RUN wget https://ftp.postgresql.org/pub/source/v8.1.4/postgresql-8.1.4.tar.gz
RUN tar -xzf postgresql-8.1.4.tar.gz
RUN apt-get install libreadline-dev -y
RUN cd postgresql-8.1.4 && ./configure CFLAGS="-O2" CC=clang && make && make install

RUN mkdir /usr/local/pgsql/data
RUN useradd -ms /bin/bash postgres
RUN mkdir -p /usr/local/pgsql/data/
RUN mkdir /usr/local/pgsql/log
RUN chown -R postgres /usr/local/pgsql/ 

USER postgres
RUN /usr/local/pgsql/bin/initdb -D /usr/local/pgsql/data

COPY freq1_data.dump /cnx_data/

从正在运行的容器中执行：

此最后一个命令返回大量错误：

我觉得我缺少一些东西。就像定义模式一样，但是我不知道该怎么做。

编辑1：运行后：create schema smdata

我得到错误：

postgres@323cadf989cf:/$ cat /tmp/error.log | head
pg_restore: [archiver (db)] Error while PROCESSING TOC:
pg_restore: [archiver (db)] Error from TOC entry 2439; 1259 2506496895 TABLE freq1_data postgres

似乎它没有从旧数据库复制架构。

您也应该转储序列：

pg_dump -U postgres -t freq1_data_id_seq -t freq1_data -F c -f /data/misc/luca/freq1_data.dump cnx
