在转储文件上使用pg_restore

Question

I have a database on Heroku I'm trying to copy to my local machine.

I created a backup of the database by doing:

heroku pgbackups:capture

This create a dump file of the database which I downloaded by creating a URL link to it:

heroku pgbackups:url b004

But now I have a dump file and don't really know what do to with it. I tried

pg_restore

to restore the database but I don't know where that information went. I basically want to create a .db file out of this dump file. Is that possible?

Ultimately my end goal is to access this database -- so if another method of copying the db is better, I'm fine with that that.

Answer 1

Heroku does not allow you to use sqlite files, as they have a read only file system. But you can use Django to dump the data from Heroku into a JSON file via the dumpdata command, and them import that into your local dev environment.

Because it can be difficult to run commands that generate files on the web server using heroku run , I suggest you instead install django smuggler , which makes this operation a point and click affair in admin.

Answer 2

First of all you should install postgres in your local machine.

Then, import your dump file with pg_restore command:

pg_restore -d yournewdb -U yournewuser --role=yournewuser /tmp/b001.dump

Thats all, your data is now cloned from your heroku app.
