Right Click on newly created Database & select Restore option from menu (Restore dialog will get opened)
Just Browse the dump file and keep other options as it is.

(1) Do not just copy-paste and run the content of dump file into either "psql promt in terminal" or "query tool of pgadmin".
(Because dump file contains COPY commands not INSERTS,So doing such will cause errors.)
(2) Replace your configurations(host,port,username) in pg_restore command
(3) Table names are suffixed with question number.
