Question

我是管理Postgresql 10数据库的新手，请耐心等待（我来自Oracle背景）。我希望一个善良的灵魂能够为我当前的问题指明正确的方向。

我们使用pg_base来备份当前的生产系统，由于某些原因，几天前pg_base停止了备份数据库的pg_control文件以及postgres.conf，这当然使备份无法恢复。

下面是我们用来启动备份的命令

 /usr/bin/docker exec -i --user postgres asf-db1 pg_basebackup --wal-method=fetch -D /var/lib/postgresql/data/pgdata/master_backup/latest -P -v --format=tar

日志中没有任何可疑的信息，只有在执行测试还原后问题才变得明显。

下面是备份日志的一部分

Postgresql 10 pg_basebackup不备份pg_control文件
