db:create misreports database existence

Hello Experts.

After creating a new site with commands

rails new board --skip-bundle
...
rake db:create

I have message like "XXXXX already exists" which is not consistent and indicates that something goes wrong.

Reproducing:

rails new board --skip-bundle
...
$ rake db:migrate
rake aborted!
FATAL:  database "boardio" does not exist

Tasks: TOP => db:migrate
(See full trace by running task with --trace)

If to try to create db then:

$ rake db:create
boardio already exists

It says here "exists". It just said "does not exist": Why rake gives a wrong message? What is going wrong? After this migration seems runs OK:

$ rake db:migrate
==  CreateMyTables: migrating =================================================
-- create_table("users")
NOTICE:  CREATE TABLE will create ........column "users.id"
.............

Details about versions:

$ ruby --version
ruby 1.9.2p290 (2011-07-09 revision 32553) [i686-linux]

$ rails --version
Rails 3.1.3

Thank you.
