What I did:
sudo -u postgres psql
CREATE ROLE shop CREATEDB LOGIN PASSWORD 'kurt1245';
Then I cloned a repository from GitHub (a rails application which uses pg), bundle install, edit database.yml to write my password and now after rake db:create (also setup and migrate) doesn't work.
database.yml:
development:
adapter: postgresql
encoding: unicode
database: shop_development
pool: 5
username: shop
password: kurt1245
test:
adapter: postgresql
encoding: unicode
database: shop_test
pool: 5
username: shop
password: kurt1245
Please Add host to your database.yml file. Hope it will help you.
development:
adapter: postgresql
encoding: unicode
host: localhost
database: shop_development
pool: 5
username: shop
password: kurt1245
test:
adapter: postgresql
encoding: unicode
host: localhost
database: shop_test
pool: 5
username: shop
password: kurt1245
I've had the same error a few days back.
Edit the /etc/postgresql/$version/main/pg_hba.conf
You can check what version you're using in the psql console as select VERSION();
Inside pg_hba.conf change
local all postgres peer
to:
local all postgres md5
Peer Authentication explained
19.3.7. Peer Authentication
The peer authentication method works by obtaining the client's
operating system user name from the kernel and using it as the allowed
database user name (with optional user name mapping). This method is
only supported on local connections.

Just followed the "Migrating to PostgreSQL" Railscast, migrating my local sqlite3 database to postgres:
here is my database.yml file:
development:
adapter: postgresql
encoding: unicode
database: app_development
pool: 5
host: localhost
username: martinbraun
password:
test:
adapter: postgresql
encoding: unicode
database: app_test
pool: 5
username: mbraun
password:
production:
adapter: postgresql
encoding: utf8
database: app_production
pool: 5
username: mbraun
password:
My postgres server is running on postgressapp on port 5432. It tells me that it's running and I get connection to my database app_development.
However, "which psql" tells me:
/usr/bin/psql
and when I start my app, all the records are not loading, I simply see my application layout and all html stuff which is not related to any records. No error is showing up.
I have verified that my database contains data via rails console, so the migration from sqlite3 to postgres was def successful. I am just wondering why my records are not showing and what I do wrong here?
I updated my database.yml file to look like so:
test:
adapter: postgresql
encoding: unicode
database: startpoint_test
hostname: localhost
pool: 5
username: postgres
password: password
development:
adapter: postgresql
encoding: unicode
database: startpoint_dev
pool: 5
username: postgres
password: password
And now it seems when I run my application, and sign up a new user the development database does not get a new user inserted into it ...
The tests all pass for signing up a new user
Have you tried using
rake db:create:all
and then
rake db:test:prepare
I am in the process of migrating my SQL to Postgresql because I want to develop in the same environment as my production.
I installed Postgres and was able to set my database yml file such that rake db:create:all worked with no problems.
However before I pushed, I realized that the username and password of the postgresql database is only available on my computer. I.e. I created the login role on my computer. When my friend who is also developing on the application, pulls the code, he won't have the username and password created by me on my computer.
Is he supposed to also create the same login role? Or is there a way to leave username / password blank so that everyone who develops can access the application? More importantly, what is the best practice for a situation like this?
I am developing on windows and he is on mac.
My database.yml: username and password left out.
development:
adapter: postgresql
encoding: unicode
database: volatility_development
pool: 5
timeout: 5000
host: localhost
test:
adapter: postgresql
encoding: unicode
database: volatility_test
pool: 5
timeout: 5000
host: localhost
production:
adapter: postgresql
encoding: unicode
database: volatility_production
pool: 5
timeout: 5000
one possibility would be to use a combination of erb and environment variables, for example:
development:
username: <%= ENV['USERNAME'] %>
password: <%= ENV['PASSWORD'] %>
adapter: postgresql
encoding: unicode
database: volatility_development
pool: 5
timeout: 5000
host: localhost
then you could do either of the following:
start your server like so: USERNAME=bob PASSWORD=secret rails s
add the following to your .bashrc
export USERNAME=bob
export PASSWORD=secret
I generated my rails app with the default SQLite database, but after creating a few models and migrating a few times, I want to change it to Postgresql.
I added the postgres gem to my Gemfile, bundle install, then I replaced all my database.yml code from
development:
adapter: sqlite3
database: db/development.sqlite3
pool: 5
timeout: 5000
test:
adapter: sqlite3
database: db/test.sqlite3
pool: 5
timeout: 5000
production:
adapter: sqlite3
database: db/production.sqlite3
pool: 5
timeout: 5000
to
default: &default
adapter: postgresql
encoding: unicode
pool: 5
username: postgres
password: mypass
development:
<<: *default
database: sample_app_development
test:
<<: *default
database: sample_app_test
production:
<<: *default
database: sample_app_production
I get a FATAL: password authentication failed for user "postgres" error even though the password is correct. Is it because I am missing a step? Am I supposed to tell PG using pg Admin III that I want to add this app to my server? Am I supposed to create a new role/connection?
I have run into this problem a few times and don't seem to be able to find an answer for this specific problem.
it gives me this when I try to run rake db:drop :
Couldn't drop sample_app_development : #<PGError: FATAL: role "postgres" does not exist
>
Couldn't drop sample_app_test : #<PGError: FATAL: role "postgres" does not exist
>

Edmunds-MacBook-Pro:sample_app edmundmai$ createuser foo

Shall the new role be allowed to create databases? (y/n) y

Postgres user authentication is a bit weird. The default is to use the same authentication as the OS (at least in Linux). So to get to the Postgres prompt from the command line, you have to do something like this:
sudo -u postgres psql
Note that there's no password - and because the OS takes care of the authentication, there's no need for one (the OS'll ask for your sudo password, though, if required).
So option one is to just strip the password option out of your Rails config file and hope everything works out. Failing that, set up Postgres to accept password-based authentication by editing the pg_hba.conf file (mine's at /etc/postgresql/9.2/main/pg_hba.conf). Here's an example from my local server; the user "postgres" uses the OS's authentication ("peer"), but the user "opengeo" uses a password ("md5"):
# TYPE DATABASE USER ADDRESS METHOD
local all postgres peer
local all opengeo md5
Hope that helps!
To convert your database to postgresql first create a user as below:
$ createuser foo
Shall the new role be a superuser? (y/n) n
Shall the new role be allowed to create databases? (y/n) y
Shall the new role be allowed to create more new roles? (y/n) y
To create a db:
CREATE DATABASE foo_db ENCODING 'UTF8' OWNER foo;
make sure your database.yml looks as below:
development:
adapter: postgresql
encoding: unicode
database: foo_db
pool: 5
username: foo
password:
test:
adapter: postgresql
encoding: unicode
database: foo_test
pool: 5
username: foo
password:
development:
adapter: postgresql
database: postgres
username: postgres
password: ;ernakulam
pool: 5
timeout: 5000
test:
adapter: postgresql
database: postgres
pool: 5
timeout: 5000
production:
adapter: postgresql
database: postgres
pool: 5
timeout: 5000`
I'm created project. Works in development mode! Excellent!
DEVELOPMENT:
Typing : ruby lib/scripts/test_sync.rb
And my script works!
PRODUCTION:
Typing : ruby lib/scripts/test_sync.rb
Get Access denied for user 'root'#'localhost' (using password: YES)
Dont know, I did everything. grant previligies, changed password and so on... Coul someone help me, please?
