NOTICES for sequence after running migration in rails on postgresql Application

Using PostgreSQL for development & test databases (as well as production). When I rake db:test:prepare my PostgreSQL theapp_test database I get these messages for each table:

NOTICE:  CREATE TABLE will create implicit sequence "events_id_seq" for serial column "events.id"
NOTICE:  CREATE TABLE / PRIMARY KEY will create implicit index "events_pkey" for table "events"
NOTICE:  CREATE TABLE will create implicit sequence "users_id_seq" for serial column "users.id"
NOTICE:  CREATE TABLE / PRIMARY KEY will create implicit index "users_pkey" for table "users"
...

I do not get these notices with rake db:migrate on theapp_development. And I haven’t noticed them in production. What does it mean and should I work to get rid of them?

FYI – This didn’t occur in the past when I have used MySQL (or SQLite3 for that matter) for testing…

No. That’s just Postgres being awesome and automatically creating stuff for you that you actually want. It’s not a warning it’s just an FYI
