Postgres permission denied to create database on rake db:create:all

Question

I am trying to create postgres databases for development and tests.

I\'m using...

• OSX Yosemite
• Rails version: 4.2.0
• git version: 2.2

Answer 1

Looking at your schema your credentials for development and test are different.

Perhaps remove username and password from the schema, seeing that your test database did get created.

Answer 2

I have faced same issues when running rake db:test:prepare in postgresql on my Ruby on Rails project. This is pretty clear from the error message, that its a permission issue for the user. I added CREATEDB permission for new_user as following from the console.

To access postgres console:

$ sudo -u postgres -i

postgres@host:~$ psql

In there:

postgres=# ALTER USER new_user CREATEDB;

It's working perfect for now. You may have another issues with database ownership, for this you can change database privileges and owner as following command.

postgres=# GRANT ALL PRIVILEGES ON  DATABASE database_name to new_user;
postgres=# ALTER DATABASE database_name owner to new_user;
