debian cron.d and security

            Hello ,

    I have the following problem :
- I use postgresql 6.5.3 on a debian
- >i want the maximun of security for my database
->so , i use  a flat file for identification by password (is it the
maximum ?) :

local                                     password   passwd

->but the cron do.maintenance don't have the password , so he failed
-> It's said that i have tu put -u postgres -p <password> on
/etc/cron.d/posgresql

BUT i don't want to see any password in clear in a file even if root
only is able to read this file !

Is there a way to make this ?

                                            thanks
