I want a script to backup all databases table by table in different .sql

Why? It may be that pg_dump / pg_restore already provide the
functionality you are looking for.
How to do this ?
pg_dump -t tablename dbname
rinse repeat
Also since it is a script, there has to be some role having read access to
all tables on all databases. How to grant that ?
Can they just be a superuser? Or can you grant them the role that has
ownership of the tables?
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.
