I have now captured the network traffic and I think the culprit is a mail sent 
by the logcheck service via the local nullmailer MTA. The message contains a 
postgresql log where a big amount of garbage has been recorded that has been 
tried to execute in postgres which it denied to do.

This looks a bit like that:
