Hello everyone,

It seems im missing something, but couldn't found anything related to this. Im using jdbc input plugin to collect some data from postgresql db.

> _[2021-05-28T03:24:12,032][ERROR][logstash.inputs.jdbc][main][_\*\*\*\*\*\*\*\*\*\*\*] Java::OrgPostgresqlUtil::PSQLException: ERROR: relation "pg\_stat\_statements" does not exist Position: 58:  
> select pu.usename, pss.query, pss.calls, pss.”rows”  
> from pg\_stat\_statements pss, pg\_user pu  
> where pss.userid=pu.usesysid  
> order by 3 desc;

> _[2021-05-28T03:24:12,109][WARN][logstash.inputs.jdbc][main][_\*\*\*\*\*\*\*\*\*\*_] Exception when executing JDBC query {:exception=\>"Java::OrgPostgresqlUtil::PSQLException: ERROR: relation "pg\_stat\_statements" does not exist\n Position: 58"}_

```auto
**configuration**
input {
jdbc {
jdbc_connection_string => "jdbc:postgresql://database.com:5432/mydatabase"
jdbc_user => "user"
jdbc_password => "password"
jdbc_driver_class => "org.postgresql.Driver"
statement_filepath => "statementpath.sql"
sql_log_level => "warn"
}
}

**statement**
select pu.usename, pss.query, pss.calls, pss.”rows”
from pg_stat_statements pss, pg_user pu
where pss.userid=pu.usesysid
order by 3 desc;

```

btw; Does this error message come from postgresql or jdbc input plugin does generate it?
