每次我重新启动我的 Kali 机器时，我的 postgresql 服务都无法正常启动。有一段时间我不知道它是什么，但我很快发现这个目录和文件一直被删除。
/var/run/postgresql/10-main.pg_stat_tmp/global.stat
跑完之后，
mkdir /var/run/postgresql/10-main.pg_stat_tmp
touch global.stat
我现在可以成功启动服务了。
但是，这是我的 postgresql.log 的输出。

这就是 postgresql.conf 里面的内容
# The default values of these variables are driven from the -D command-line
# option or PGDATA environment variable, represented here as ConfigDir.
data_directory = '/var/lib/postgresql/10/main' # use data in another
directory
# (change requires restart)
hba_file = '/etc/postgresql/10/main/pg_hba.conf' # host-based
authentication file

ident_file = '/etc/postgresql/10/main/pg_ident.conf' # ident
configuration file

这是 Postgres 版本 10。
