I don't feel safe to key in the root password in the script.
I was previously using MySQL, in which I had a user called backup
without password having SELECT access on all tables and databases.
I need something similar in PgSQL. A possible solution seems to me is to
use the trust auth for a user in pg_hba.conf, but if the user is given
superuser status, then it will have write access to all databases, which
is extremely dangerous.
