That's probably because of the configuration in the pg_hba.conf
file:

http://www.postgresql.org/docs/current/interactive/auth-pg-hba-conf.html

or maybe the .pgpass file:

By the way, I would seriously consider setting this for a "database
superuser" login related to an OS login which owns the database,
rather than the root account.  Using root anytime it's not
absolutely necessary is generally not good practice.
