No I can not trust the clients administrators.

I have played now with MySQL and with MySQL you can change the password
for root in MySQL (same as postgres in PostgreSQL). If you use the
command line tools like dump you require the password. Just because
your root doesn't mean your root in MySQL

Can one separate the user postgres in PostgreSQL from the user postgres
in Linux(The OS)?
