- A TypeDecorator of Integer can be used with a primary key

- A TypeDecorator of Integer can be used with a primary key
  column, and the "autoincrement" feature of various dialects
  as well as the "sqlite_autoincrement" flag will honor
  the underlying database type as being Integer-based.
 [ticket:2005]

- Result-row processors are applied to pre-executed SQL
  defaults, as well as cursor.lastrowid, when determining
  the contents of result.inserted_primary_key.
  [ticket:2006]

- Bind parameters present in the "columns clause" of a select
  are now auto-labeled like other "anonymous" clauses,
  which among other things allows their "type" to be meaningful
  when the row is fetched, as in result row processors.

- TypeDecorator is present in the "sqlalchemy" import space.
