我无法恢复我的Postgres服务器12。我有群集，2个服务器PSQL12s01、PSQL12s02。在arch_log复制之间。数据库大小约为45 GB + 400 GB arch_log。我在从服务器上运行脚本

D=$(date +%Y%m%d%H%M)
sudo -u postgres -H bash -c "pg_basebackup -l db_TECH_$D -D - -Ft -X fetch | bzip2 > /var/lib/postgresql/BKP/db_TECH_$D.tar.bz2"

文件在REST服务器上解压缩并运行docker container

docker run -d \
    --name tc12s02-postgres \
    -e POSTGRES_PASSWORD=postgres \
    -e PGDATA=/var/lib/postgresql/data/pgdata \
    -p 15432:5432 \
    -v /var/lib/postgresql/BKP:/var/lib/postgresql/data/pgdata \
    -v /var/lib/postgresql/SMB/arch_log:/var/lib/postgresql/data/pgdata/arch_log \
    postgres:12

当我的启动容器日期为2022年10月17日时

restore_command = 'cp /var/lib/postgresql/data/pgdata/arch_log/%f %p'
recovery_target_time = '2023-02-18 20:00:00'
recovery_target_action = 'promote'

touch recovery.signal

我不知道为什么我不想访问arch_log中的数据。也许我必须为不在从机上的主机执行pg_basebackup。我不想给主机增加额外的负担
