Get the Heroku db as detailed here:
http://devcenter.heroku.com/articles/pgbackups#exporting_via_a_backup

1. heroku pgbackups:capture
2. heroku pgbackups:url <backup_num>  #=>backup_url
   -  get backup_num with cmd "heroku pgbackups"
3. curl -o latest.dump <backup_url>

Then locally do:
$ pg_restore --verbose --clean --no-acl --no-owner -h localhost -U myuser -d mydb latest.dump

(your database must exist before can do this)
