If you have numeric password for your database, like below:
```yaml
development:
adapter: mysql2
encoding: utf8
database: myblog_development
pool: 5
username: root
password: 123456
```
you will get the following obscure error with unhelpful stack-trace
```shell

Looking [Can't convert fixnum to string during rake db:create](http://stackoverflow.com/questions/3765834/cant-convert-fixnum-to-string-during-rake-dbcreate), it seems lot of people have faced the same error.
so adding a note informing about numeric passwords seems like a good idea
