Bug fixes

• Fix a limitation where only one nameless join could be given to a query
• Ensure duplicated preloads are loaded only once
• Ensure p.field in select returns the proper field type

Backwards incompatible changes

• Ecto.Adapters.Postgres.query/4 has been renamed to Ecto.Adapters.SQL.query/4
• Ecto.Adapters.Postgres.begin_test_transaction/2 has been renamed to Ecto.Adapters.SQL.begin_test_transaction/2
• Ecto.Adapters.Postgres.rollback_test_transaction/2 has been renamed to Ecto.Adapters.SQL.rollback_test_transaction/2
• Mix tasks now expect the repository with the option -r, otherwise it defaults to the application based one
• :datetime, :time and :date will now return tuples in Ecto queries. To keep the previous behaviour, please replace the types in your schema with Ecto.DateTime, Ecto.Time and Ecto.Date
• Ecto.Changeset.validate_change/4 now passes the field and value to the callback function instead of only the value
