If you *really* want root to be able to login to the database as the
postgres user using ident authentication, then you're going to need to
add a line to pg_hba.conf using an ident map, then in the ident map
you're going to have to allow root to map to postgres.

root, per default, does not have a user in postgres. Run your script as
the postgres user if you *really* want super user access.
