# Wipe A Heroku Postgres Database
|
|
|
|
If you have some sort of non-production version of an application running on
|
|
Heroku, you may encounter a time when you need to wipe your database and
|
|
start fresh. For a rails project, it may be tempting to do `heroku run rake
|
|
db:drop db:setup`. Heroku doesn't want you to accidentally do anything
|
|
stupid, so it prevents you from running `rake db:drop`. Instead, you must
|
|
send a more explicit command
|
|
|
|
```
|
|
$ heroku pg:reset DATABASE_URL
|
|
```
|
|
|
|
Heroku will ask you to confirm that you indeed want to wipe out the database
|
|
and will then proceed.
|
|
|
|
For the curious reader, running `heroku config` will list the values of a
|
|
number of variables including `DATABASE_URL`.
