I have a problem, I pushed my app to github and I made the deploy with heroku, everything was ok, but when I run heroku run --app myapp rake db:reset (to populate the database on heroku) I found the following messages filled with errors (I show only the part that I think is important because the message was too long)
FATAL: permission denied for database "postgres"

Everything works fine in the deployed app, but I find ugly to see so many mistakes when making a rake db: reset in heroku, so after seeing this I searched how to solve this problem and found some posts that preach the same solution, so I followed the recommendations and run the command heroku pg:reset DATABASE_URL --app myapp, it ended succesfully, but the same error message appears when I tried again to run rake db:reset, What could be happening?
This is my database.yml
development:
adapter: postgresql
encoding: utf8
database: project_development
pool: 5
username:
password:
test:
adapter: postgresql
encoding: utf8
database: project_test
pool: 5

production:
adapter: postgresql
encoding: utf8
database: project_production
pool: 5

Heroku, being a shared service is not allowing users the permissions to drop nor create databases - hence the error when running rake db:reset
Hence heroku pg:reset is present as a command to perform the reset of your database.
See https://devcenter.heroku.com/articles/rake
I got the same error I have fixed it by
heroku pg:reset DATABASE_URL
heroku rake db:migrate
As per you error
Also your database.yml point postgres user to connect database in heroku
it should not be postgres as a user in production mode.
so
Active Record 4.1+ Escape Valve
If you need need to connect to a different database than the
ENV['DATABASE_URL'] Rails 4.1+ supports a URL key in the database.yml
file that will take precedence.
production:
url: <%= ENV["SOME_OTHER_URL"] %>

I've spend several hours figuring out how to get my database up and running. I created a new rails app and wanted to deploy it to heroku. I followed the instructions from heroku (to switch from sqlite3 -> postgresql) but it just doesn't work.
This is in my database.yml file:
default: &default
adapter: postgresql
pool: 5
timeout: 5000
development:
<<: *default
database: myapp_development
test:
<<: *default
database: myapp_test
production:
<<: *default
database: myapp_production
url: <%= ENV['DATABASE_URL'] %>
I can't create or seed any data in the database. Sometimes it executes the db:migrate, but even then it doesn't create anything. This is what I get when running:
heroku run rake db:create
FATAL: permission denied for database "postgres"
DETAIL: User does not have CONNECT privilege.
Does anyone has an idea on how to solve this? I don't have a clue anymore ...
Thanks!
By default you don't need to create a db on heroku.
Just run heroku run rails db:migrate and rest of the stuff will be handled by heroku itself.
Also your database.yml should be changed to following for Production env.
production:
<<: *default
database: myapp_production
username: myapp
password: <%= ENV['MYAPP_DATABASE_PASSWORD'] %>
Also your rails app is by default assigned with a Postgres addon.
You can check this by running command heroku addons in the console.

Heroku Getting Started Guide
Heroku Postgres Addon Guide
You cannot create a database on Heroku using db:create (you cannot drop it neither). Your database is created when you add an add-on (such as Heroku Postgres). You can only migrate and seed. And if you want to start over, you can use pg:reset (instead of drop and create)
So the correct sequence should be:
add the Heroku add-on (such as Heroku Postgres). Add-ons are located here: https://elements.heroku.com/addons.
rake db:migrate
rake db:seed
if you want to start over
rake pg:reset
rake db:migrate
rake db:seed
From Heroku documentation: https://devcenter.heroku.com/articles/heroku-postgresql
The PostgreSQL user your database is assigned doesn’t have permission to create or drop databases. To drop and recreate your database use pg:reset.
As per the given stacktrace, it seems like you are trying to create a database on heroku which in turn is giving you Permission Denied Error.
Firstly, you do not need to run
heroku run rake db:create
Instead run
heroku run rake db:migrate
and it should migrate the migrations which are down.
For checking the current status of migrations run the following command:
heroku run rake db:migrate:status
Other Point you mentioned:
-> I can't create or seed any data in the database
As already mentioned above you can't create a database as heroku does it for you .
For seeding data in the database run the following command:
heroku run rake db:seed
This is my database.yml
production:
adapter: mysql2
encoding: utf8
database: testing
pool: 5
username: ubuntu
host: 127.0.0.1
When I run rake db:setup I got this:
Couldn't create database for {"adapter"=>"mysql2", "encoding"=>"utf8", "database"=>"testing", "pool"=>5, "username"=>"ubuntu", "host"=>"127.0.0.1"}
-- create_table("documents", {:force=>:cascade})
rake aborted!
Mysql2::Error: Access denied for user ''#'localhost' to database 'testing'
Why it's not using my username and host? instead is showing '' # 'localhost'
I think, database.yml config for production environment, but you run it on development environment. You can use 'RAILS_ENV=development rake db:setup' or 'RAILS_ENV=test rake db:setup'
One more thing, database should be created by mysql user with root privileges
its been a while since i have used postgresql and deployed an app to Heroku, think I have made an error somewhere with my setup.
I have created my app on Heroku, there is a Hobby Dev database setup (I ran Heroku run rake db:setup) which set up my database, but I'm wondering in my database.yml file do i have an error
default: &default
adapter: postgresql
encoding: unicode
# For details on connection pooling, see rails configuration guide
# http://guides.rubyonrails.org/configuring.html#database-pooling
pool: 5
production:
<<: *default
database: my_app_production
username: my_app
password: <%= ENV['MY_APP_DATABASE_PASSWORD'] %>
When I run heroku run rake db:create i get
FATAL: permission denied for database
DETAIL: User does not have CONNECT privilege.
Couldn't create database for {"adapter"=>"postgresql", "encoding"=>"unicode", "pool"=>5, "database"=>"databaseName", "username"=>"userName", "password"=>"password", "port"=>5432, "host"=>"hostNamehere"}
I have set the database password using heroku config:set
What have i missed here?
Thanks
Heroku ignores your database.yml configuration, they generate one when you deploy your application and they also take care of database creation.
All you need to do is heroku run rake db:migrate and maybe a heroku run rake db:seed in case you need to seed your database.
So I seemingly successfully installed postgres for production for heroku deployment, but locally rails seems to not find/nor create the database.
When I go to localhost:3000 I get the error:
ActiveRecord::NoDatabaseError
FATAL: database "dimension_development" does not exist Run `$ bin/rake db:create db:migrate` to create your database
When I run $bin/rake db:create I get:
~ already exists
Then, run db:migrate and restart the rails server, reload the page, and get same error.
So I tried instead to run $bin/rake db:create:all and got:
~ already exists
dimension_test already exists
dimension_production already exists
Then did db:migrate again but nothing changed.
If they already exist, why isn't rails finding them? I notice that in the config/db folder there is still the old development.sqlite3 file but no postgres file.
Any idea what could be going on to cause this error?
My database.yml is:
development:
adapter: postgresql
database: dimension_development
pool: 5
timeout: 5000
test:
adapter: postgresql
database: dimension_test
pool: 5
timeout: 5000
production:
adapter: postgresql
database: dimension_production
pool: 5
timeout: 5000
Thanks! This has got me stumped and I haven't been able to find anything on stackoverflow dealing with this pitfall.
In case of postgresql you will not find any file like development.sqlite3. It's in case of sqlite only.
You did not provided database credential in your database.yml file might causing this error. Try pass username and password as well.
development:
adapter: postgresql
database: dimension_development
pool: 5
timeout: 5000
username: xxxx
password: xxxx
I have PostgreSQL installed via this link and all seems good. I can use the GUI interface and I can see my databases but when I run rake db:migrate I get the following error:
$ rake db:migrate
(in /Users/tamer/Sites/sample)
rake aborted!
FATAL: password authentication failed for user "tamer"
(See full trace by running task with --trace)
Here is my database.yml file:
development:
adapter: postgresql
database: test
encoding: unicode
host: localhost
user: postgres
password: mypass
timeout: 5000
Where "mypass" is my password I set.
Here is a picture of it running
Any ideas what i am doing wrong?
Well something doesn't quite add up. The error message refers to a user "tamer" but the database.yml file has the "postgres" user. Are you sure this is the database.yml file that's being used? What happens when you try to log in with the GUI tool with either user?
