How we work

Download staging data to local machine

Please refer to previous article to understand the names we are using in this article.

First take a backup

1heroku pg:backups:capture -a wheel-staging

Download the backup file

1heroku pg:backups:download -a wheel-staging

It will download a file called latest.dump.

Update local database with downloaded file

1pg_restore --verbose --clean --no-owner --no-privileges --dbname=wheel_development latest.dump

In the above case replace wheel_development with the name of the database you have.


You might get error something siimilar to as shown below.

1pg_restore: [archiver] unsupported version (1.13) in file header

It probably means that the version of pg_dump used by heroku is not as the version we are running locally.

First let's check the version running in heroku.

1> heroku run bash -a wheel-staging
2> pg_dump --version
4pg_dump (PostgreSQL) 10.3 (Ubuntu 10.3-1.pgdg14.04+1)

It seems heroku is using version 10.3.

Now let's check our local version of pg_restore.

1> pg_restore --version
3pg_restore (PostgreSQL) 10.0

As we can see that heroku used pg_dump version "10.3". Our pg_restore version is "10.0"

Time to upgrade postgresql. Execute brew upgrade postgresql.
