That's what I got in the log file, and I don't know why I got this in every log file. The database and even the Debian system all are newly installed, less than a week, and I didn't make any scanner thing anywhere yet. The only tool I know that is related to postgresql is the pgAdmin3 , which I installed after the postgresql. So what has gone wrong? It's dengerous. Any one can tell me how I can track this done to find out? What I should do exactly? Any help from anyone would be highly appreciated! Will reinstallation help? leo __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com
