I think maybe you can check the pg_hba.conf, change the method to the 'trust'.
(Allow the connection unconditionally. This method allows anyone that can connect to the PostgreSQL database server to login as any PostgreSQL user they wish, without the need for a password or any other authentication. See Section 21.4 for details.)
And then login as the root user, after that do the things you wish.
