I'am work with postgresql DB , and i want to secure it from users .
I read about pg_hba.conf it have many method , and i wonder about trust method .
if i have a password on my server and i don't want to users to enter the server and open it , how i can prevent the trust method to prevents them to open it ?
i know about MD5 and other method , but if anyone access the pg_hba.conf file and change it to trust will open so i don't want to let users open server even the method change to trust ?
