[Rails] Rails 3 requires SQLite?

I've installed latest Rails on Centos 5.5, created a test app with
"rails new test1", and changed the datatabase config in config/
database.yml to PostgreSQL. "rails server" fails because SQLite is
missing. Why is it looking for SQLite when database.yml says
PostgreSQL?

Thanks for any help.
