syslog message I do not understand

[Art Fore <art.fore@xxxxxxxxxxx>]

I am trying to start postgresql via webmin, but not having success. I 
get a message in the syslog "su:(to postgres) root on none"

This is suse 9.3. Could someone tell what that message means?

I was working until I added the -i to the postmaster.opts file so I 
could access it via pgadmin.
