Hi,I try to synchronize postgres to elastic.  
But I receive the error below and not update index data.  
Is it necessary to make multiple pipelines or something?

`Logstash could not be started because there is already another instance using the configured data directory. If you wish to run multiple instances, you must change the "path.data" setting.`

my conf is like this,

```
input {
   jdbc {
     jdbc_driver_library => "/usr/share/java/postgresql-42.2.8.jar"
     jdbc_driver_class => "org.postgresql.Driver"
     jdbc_connection_string => "jdbc:postgresql://192.168.9.9/data"
     jdbc_user => "user"
     jdbc_password => "password"
     statement => "select * from database where collect_time>:sql_last_value"
     schedule => "* /10 * * * * *"
   }
}

output {
  elasticsearch {
    hosts => "localhost:9200"
    index => "data"
    document_type => "router"
    document_id=> "log-20%{+YY-MM-dd-hh-mm-ss}"
  }
}

```

regards,
