Such kind of questions are better to ask on ServerFault. You have to provide pg_dump with the valid postgresql account via command line parameter:

pg_dump -U postgres nsdgpkidb > file.sql

By default it assumes the current local user account (root). Another way is to change the current user and issue the command.
