rake db:create vs rake db:create:all

Question

What is the difference between rake db:create and rake db:create:all?
Both are equally used in order to create a database for a Rails application.
The most exhaustive information on rake for Rails I could find is at tutorialpoint but the above commands are missing.

rake db:create:all creates all the databases for the application (which are defined in database.yml)
rake db:create creates the database for the current RAILS_ENV environment. If RAILS_ENV is not specified it defaults to the development and test databases.

One creates the DB for the current environment.

If you run rake -T | grep db, you will see :

rake db:create 
# Creates the database from DATABASE_URL or config/database.yml for the current RAILS_ENV
# (use db:create:all to create all databases in the config)
