I am trying to copy my local Postgres database to Heroku.
So I use pg:backups:restore from a publicly accessible URL.
As mentioned in the documentation, I have downloaded my Postgres dump to Amazon S3 and gave the public access. The link to file is: https://s3.eu-west-2.amazonaws.com/kirillch/localizedb.sql.
So now I run a command:
heroku pg:backups:restore 'https://s3.eu-west-2.amazonaws.com/kirillch/localizedb.sql' DATABASE_URL -a my_app_name
and get an error:
Backup https://s3.eu-west-2.amazonaws.com/kirillch/localizedb.sql
not found for my_app
What could be done to fix the issue?
For windows users;
heroku pg:backups:restore "https://s3.amazonaws.com/me/items/3H0q/mydb.dump" DATABASE_URL
According to the official docs, be sure to use double-quotes around the remote url if you're using windows. see official docs

I configured the database in application.properties with the spring.datasource.url property, using the DATABASE_URL that I see when running
heroku config
from terminal
I get "Postgresql Driver Claims to not accept JDBC URL" error when running the app from IntelliJ.
Tried solutions in thispost, but none of them helped.
I am deployiong on Heroku Postgres.
I found a working solution in Heroku docs.
The correct jdbc url can be accessed through the heroku cli in your terminal:
heroku run echo \$JDBC_DATABASE_URL
I put the url into src/main/resources/application.properties like this:
spring.datasource.url=<your jdbc url>
Currently I have my Ruby on Rails program running great on my Linux Ubuntu development environment, and now I want to run it live on my website, and get it hosted on Heroku.
The problem is that I don't know how to create a user and a database on Heroku. I have tried the command
heroku run rake db:create
I got the error:
permission denied for database - user does nothave connect privilage
I also tried the command
heroku run su - postgres
and it posted that I need to use the terminal so I do not know how to proceed.
This is my database.yml
default: &default
adapter: postgresql
host: localhost
development:
<<: *default
database: app_development
test:
<<: *default
database: app_test
production:
<<: *default
database: app_production
How do I set up my database and the proper connections with my Heroku PostgreSQL database?
i also did this
heroku pg:info
which gave me this
shrouded-reaches-3063 has no heroku-postgresql databases.
also tried this
heroku addons | grep POSTGRES
but nothing was printed
heroku addons:create heroku-postgresql:hobby-dev
! `addons:create` is not a heroku command.
! See `heroku help` for a list of available commands.
also this
heroku pg:wait
and displayed nothing... this really is something T_T really need some major help here , and will be really greatful for any help
Have you provisioned a database? What does heroku addons say? You can create an add-on as documented here with heroku addons:create heroku-postgresql:hobby-dev
!!!NOT IN THE DOCUMENTATION!!!
heroku addons:create heroku-postgresql:hobby-dev --version=12 --app "APPNAME" --name "APPNAME-database"
--app : Specify the heroku app you want to add the database too. Really good if you have more than one heroku app.
--name : The name you would like to give your database. I like to take my application name and postfix it with "database" as a nice convention. Better than whatever randomly generated name you'll get.
APPNAME: A placeholder for whatever your application name is.
No mention of any of this on heroku.com documentation pages for addons in general or postgres addon. I think I came to this via guessing based on documentation for creating apps. But I don't remember. This was in my notes from 5+ years ago. However, I just tried it, still works as of 2022.05.14.
I need to transfer db from app_1 to app_2
I created backup on app_1
Then ran:
heroku pg:backups restore HEROKU_POSTGRESQL_COLOR --app app_2 heroku pgbackups:url --app app_1
HEROKU_POSTGRESQL_COLOR = database URL for app_2
Then I get:
! `pg:backups` is not a heroku command.
! Perhaps you meant `pgbackups`.
! See `heroku help` for a list of available commands.
So I ran:
heroku pgbackups:restore HEROKU_POSTGRESQL_COLOR --app app_2 heroku pgbackups:url --app app_1
Then I get the following:
! WARNING: Destructive Action
! This command will affect the app: app_2
! To proceed, type "app_2" or re-run this command with --confirm app_2
So I confirmed with:
> app_2
! Please add the pgbackups addon first via:
! heroku addons:add pgbackups
So then I ran: heroku addons:add pgbackups --app app_2
Adding pgbackups on app_2... failed
! Add-on plan not found.
Is there a way around this issue? any help would be greatly appreciated!
* Solution *
I ended up emailing Heroku, they advised that I need to heroku update; heroku plugins:update but heroku update is only available to heroku toolbelt only and I had the gem installed.
Solution:
Install Heroku toolbelt here
Then uninstall the gem:
gem uninstall heroku --all
run the following to get the version and it should output heroku-toolbelt, instead of the gem, more info here
$ heroku --version
heroku-toolbelt/2.39.0 (x86_64-darwin10.8.0) ruby/1.9.3
To copy the databases over:
heroku pg:backups restore `heroku pgbackups:url --app app_1` HEROKU_POSTGRESQL_COLOR --app app_2
But even better—you can copy directly from one database to another without needing the backup:
Assuming app_2 database url is: HEROKU_POSTGRESQL_GOLD
heroku pg:copy app_1::DATABASE_URL GOLD -a app_2
That will copy the main database from app_1 to the GOLd database on app_2
its only 1 command to copy database from app to app now you don't have to backup:
heroku pg:copy app_name_to_copy_from::database_color_to_copy_from database_color_to_copy_to --app app_name_to_copy_to
check it here
If you look at heroku docs it says
PG Backups as an add-on has been deprecated. The commands exist as part of the Heroku Postgres namespace in the CLI. The new functionality is live and available for use.
So you can use the pgbackups functionality directly without having to add any add-ons
To create a backup you can run
heroku pg:backups capture --app app_name
if you have multiple databases then you can specify database url like this
heroku pg:backups capture HEROKU_POSTGRESQL_PINK
To restore from a backup on another app you can run
heroku pg:backups restore b001 DATABASE_URL --app app_name
You can transfer database by
heroku pg:copy DATABASE_URL HEROKU_POSTGRESQL_PINK_URL --app app_name
You can also upload your database to a public url and then use that url to import database on another app by
heroku pg:backups public-url b001 --app app_name
and then import it by
heroku pg:backups restore 'https://s3.amazonaws.com/me/items/3H0q/mydb.dump' DATABASE -a app_name
If you are moving from one app to another and want to use same database for another app then you can follow these steps:
Login to your heroku account
Select your old app and go to settings tab
Reveal config vars for your old app
Copy DATABASE_URL
Go back and select your new app
Replace new apps DATABASE_URL with the old apps value
I needed something slightly different so sharing it here:
heroku pg:copy name_of_app_being_copied::DATABASE_URL DATABASE_URL --app name_of_app_being_copied_to
Note: Both references to DATABASE_URL do not need to be changed. It may seem odd, but the first instance references the database url for the app being copied and the second one references the database url of the app being copied to.
heroku pg:copy app1_name::HEROKU_POSTGRESQL_ONYX_URL HEROKU_POSTGRESQL_AQUA_URL --app app2_name
Where the second db url is on app2_name
There are simple ways to do this, and there is a fast way to do it
The simple ways generally involve using a backup/restore methodology (including pg:copy, which is a backup that streams the data directly to a pg_restore process), but these are slow in creating the new database because you are restoring a logical definition of tables, loading the data, and creating indexes on the data.
That's a lot of work, and for my 30GB standard-2 databases it can literally take hours.
The fast way to do it is to provision a follower of the database to be copied (e.g. production) on the application you want the data on (e.g. test). On the same 30GB databases that take hours to do a restore, this last took about 15 minutes.
The methodology I use is:
# Get the name of the source database addon (e.g. postgresql-clean-12345)
heroku pg:info -a production-app
# Create a follower on the destination app (choose your own plan)
# You create the follower on the new app because otherwise it is
# perpetually associated with the source as it's "billing app"
heroku addons:create heroku-postgresql:standard-2 --follow postgresql-clean-12345 -a test-app
heroku pg:wait -a test-app
# Quiesce the destination app
heroku scale web=0 worker=0 -a test-app
heroku maintenance:on -a test-app
# Get the colour of the new database (e.g. HEROKU_POSTGRESQL_GRAY_URL)
heroku pg:info -a test-app
# Unfollow the source database.
# If you want to upgrade the database, do that now instead of the
# unfollow.
heroku pg:unfollow HEROKU_POSTGRESQL_GRAY_URL -a test-app
# Promote the new database on the destination app
heroku pg:promote HEROKU_POSTGRESQL_GRAY_URL -a test-app
# Get the colour of the old database, if any(e.g. HEROKU_POSTGRESQL_MAROON_URL)
heroku pg:info -a test-app
# Destroy the old database (if any)
heroku addons:destroy HEROKU_POSTGRESQL_MAROON_URL -a test-app
# Bring the test app back up
heroku scale web=1 worker=1 -a test-app
heroku maintenance:off -a test-app
Why is this faster?
I believe that when creating a follower, Heroku creates the new database by either copying data files or restoring from a physical (file) backup, then replaying the logs to bring it up to date.
I found the simpler solution to reuse/share the same resource (postgres database in this case - or any others that allow sharing/reuse) with more than one app on heroku is doing the following:
Go to the older (source) app dashboard on Heroku
Select the "Resources" tab
Locate the resource (postgres database, in our case here)
Click on the icon next to the plan name at the right most part of the row listing the resource
Select the "Attach to another app" option and select the newer (target) app name from the list that shows up
Sample of the extended menu mentioned # step #4 above!
That's all it takes to share the resource between the apps as it automatically updates all the related configuration settings on the target app. This comes handy since none of the add-on related configuration variables are directly editable, at least from the dashboard (have not checked through the CLI). Hope this helps anyone looking for similar thing.
As per the website the addon is depreciated. So that could be the reason for the failure message.
Backups as an add-on has been deprecated.
Since your aim is to move the db from one app to another, why don't you try the instructions mentioned in the link below.
https://devcenter.heroku.com/articles/heroku-postgres-backups#direct-database-to-database-copies
heroku addons:create heroku-postgresql:standard-0 --fork postgresql-translucent-12345 --app target-app
Where postgresql-translucent-12345 is the addon name of the database you want to fork from. Note that the color url does not work across different apps but the addon name does.
You can also add the "--fast" option:
heroku addons:create heroku-postgresql:standard-0 --fork postgresql-translucent-12345 --fast --app target-app
Which creates a fork of the database that could be up to 30 hours old. Even without the fast option, I copied a 40GB database in 10 minutes-ish.
https://devcenter.heroku.com/articles/heroku-postgres-fork
Then you have to, of course, promote the database. See David Aldridge's answer -and my comments- above for some further details about the process.
I had a related issue. You can save a backup to your local machine, then upload it to some hosting, like amazon s3, and import from given url.
This question and following answer may help you: Can't import to heroku postgres database from dump
You may find useful pgAdmin III (http://pgadmin.org/), a free db management tool specifically designed to do these types of tasks. You can edit/view/import/export from/to your Heroku db directly. Let me know if you need help in setup. (It's like MySQL Workbench, but for PostgreSQL).
I can't manage to share two PostgreSQL heroku dbases between two heroku apps.
Doesn't work
What I've tried so far (I'm using the Heroku CLI):
$ heroku config:set DATABASE_URL=`heroku config:get DATABASE_URL -a my-heroku-app-original`
Setting config vars and restarting my-heroku-app... done, v20
DATABASE_URL: postgres://...correct url...
$ heroku config
=== msite-poniai Config Vars
DATABASE_URL: postgres://...correct url...
When I try to access psql, depending on whether I've added a new db or not, I get these two answer (I both cases heroku doesn't see the DATABASE_URL I've just provided.
$ heroku pg:psql
! Your app has no databases.
$ heroku pg:psql
! Unknown database. Valid options are: HEROKU_POSTGRESQL_NEWLYADDED_URL
Works
If I provide psql with the exact location of the db (in this case the original app that has the db as an add-on) it does manage to connect.
$ heroku pg:psql HEROKU_POSTGRESQL_ORIGINAL_URL --app my-heroku-app-original
psql (9.1.9)
I've read
I've closely followed advice given in Share database between 2 apps in Heroku and heroku-postgresql#create-new-db.
Simply copying a config var from one app to another does not attach the referenced database to the app. Were the host or password to change on the first, your second app would be broken. There is a highly alpha plugin you can try https://github.com/heroku/heroku-attachable-resources but it does some weird things like no longer give default names to databases, and overwrites DATABASE_URL if you don't pass in --config and sometimes doesn't let you remove databases.
This is the command I have to find the name of a heroku database:
$ heroku config | grep POSTGRESQL
I get a result similar to:
HEROKU_POSTGRESQL_NAVY_URL: postgres://wxjwilh:tKDSwUlfZ8Da#fr6-84-24-28-19.compute-1.amazonaws.com:52/d14grmkt
which part of this output is the database name I can use with the command:
$ heroku pg:reset <DATABASE>
I tried using the whole url but got an invalid argument error.
hope everyone confuses with placeholder and constant.
Assume having a db with name d6u5qhrlnbdfmp. then it is NOT necessary to type
heroku pg:reset d6u5qhrlnbdfmp
Instead we can plainly type
heroku pg:reset DATABASE_URL
the sample output
E:\git\stutzen>heroku pg:reset d6u5qhrlnbdfmp --app stutzen
! Unknown database: d6u5qhrlnbdfmp. Valid options are: DATABASE_URL, HEROKU_
POSTGRESQL_CYAN_URL
E:\git\stutzen>heroku pg:reset DATABASE_URL --app stutzen
! WARNING: Destructive Action
! This command will affect the app: stutzen
! To proceed, type "stutzen" or re-run this command with --confirm stutzen
> stutzen
Resetting HEROKU_POSTGRESQL_CYAN_URL (DATABASE_URL)... done
URL consists of the following parts:
scheme://username:password#host:port/database
So, in your case DB name is d14grmkt.
I had a hard time to reset my database on Heroku. I post this, because I think it's the most straightforward solution. To find out the database name cd to your application folder and type:
heroku pg:info
Output will be something like
=== HEROKU_POSTGRESQL_BRONZE_URL
#other stuff
To reset the database type:
heroku pg:reset HEROKU_POSTGRESQL_BRONZE_URL
you have to confirm with your application name.
While using the command:
$ heroku pg:reset DATABASE
It will tell you the available database name like this:
! Unknown database: DATABASE_URL. Valid options are: HEROKU_POSTGRESQL_COPPER_URL, SHARED_DATABASE
so try the options it gave like this
$ heroku pg:reset HEROKU_POSTGRESQL_COPPER_URL
Late to the party, but if you need the db name, for example to add it as an addon to another instance, you run
heroku addons
In the list you will see your postgres addon, in the 'Add-on' column is the name of the db app that is attached
NOT MENTIONED IN THE HEROKU WEBSITE DOCUMENTATION:
heroku addons:create heroku-postgresql:hobby-dev --version=12 --app "APPNAME" --name "APPNAME-database"

--name : The name you would like to give your database. I like to take my application name and postfix it with "database" as a nice convention. Better than whatever randomly generated name you'll get.
