After establishing a database using heroku addons:create heroku-postgresql:hobby-dev, I tried to migrate my local database to heroku database. So I first ran
heroku python manage.py migrate. After that I created a dump file of my local database using pg_dump -Fc --no-acl --no-owner -h localhost -U myuser mydb > mydb.dump. I uploaded my mydb.dump file to dropbox and then used the following command to load the dump to my heroku database
heroku pg:backups restore'https://www.dropbox.com/s/xkc8jhav70hgqfd/mydb.dump?' HEROKU_POSTGRESQL_COLOR_URL
But, that throws the following error -
r004 ---restore---> HEROKU_POSTGRESQL_PURPLE
[0KRunning... 0.00B..
[0KAn error occurred and your backup did not finish.
Please run `heroku pg:backups info r004` for details.
And on running heroku pg:backups info r004 I get -

There is not much information on this error online and I can't figure out what the problem is.
If the database is small and you feel lucky this might do it
pg_dump --no-acl --no-owner -h localhost -U myuser myd | heroku pg:psql
