Hello, great!  
I really need your help.

I need to merge the lines of the same PostgreSQL event. My "/var/log/postgresql/postgresql-9.5-main.log" events are as follows:

> 2018-03-12 20:14:54 AMT [11143]: [1-1] LOG: connection received: host = 192.168.0.100 port = 45045  
> 2018-03-12 20:14:54 AMT [11143]: [2-1] LOG: authorized connection: user = portalsetorial database = portal\_setorial SSL enabled (protocol = TLSv1.2, cipher = ECDHE-RSA-AES256- GCM-SHA384, compression = enabled)  
> 2018-03-12 20:14:54 AMT [11143]: [3-1] ERROR: missing entry for table "session" in clause FROM in character 10  
> 2018-03-12 20:14:54 AMT [11143]: [4-1] COMMAND: SELECT @@ SESSION.sql\_mode  
> 2018-03-12 20:15:00 AMT [11143]: [5-1] LOG: disconnect: Session time: 0: 00: 05 817 user = portalsetorial database = portal\_setorial machine = 192.168.0.100 port = 45045

I want, for example, that all events of id "11143" be sent to the "message" field, so that I can relate them correctly through Kibaba filters.

Today my file "logstash.yml" looks like this:

> input {  
> file {  
> path =\> ["/var/log/postgresql/\*.log"]  
> type =\> "all"  
> }  
> }  
> output {  
> elasticsearch { hosts =\> ["192.168.0.67:9200"] }  
> stdout { codec =\> rubydebug }  
> }

How should I do?  
Any help is very welcome. Thank you!
