我正在尝试将planet.osm 转换为debian 上的postgresql。

sudo -u postgres dropdb osm
sudo -u postgres createdb osm
sudo -u postgres  psql -d osm -c 'CREATE EXTENSION postgis; CREATE EXTENSION hstore;'
nohup sudo -u postgres osm2pgsql -c -d osm --multi-geometry  --cache-strategy dense -C 4000 planet-latest.osm&

没有错误，osm2pgsql 写道它创建了表，但是数据库中没有任何表：

sudo -u postgres psql osm
psql (9.5.3, server 9.1.22)
Type "help" for help.

osm=# \d+
                           List of relations

这是 nohup.out 文件：

磁盘空间不会减少。它在哪里写入数据？
