zabbix server is running on server1 (with agent and Postgresql database locally).
PROD postgresql database is running on server2 (this server is monitored in zabbix with zabbix agent).

I noticed strange entries in log postgresql file on server2. log file attached.
These failing insert statements shouldnt have been executed on this server! I think zabbix agent is doing this, is it possible?
I checked that zabbix can connect to postgres localy:
root@server2:~# su - zabbix
$ psql -Upostgres
psql (8.4.12)
Type "help" for help.

postgres=#

I checked few other postgresql servers, nothing unusual there.
