Redmine

When multiple trac projects are migrated with rake redmine:migrate_from_trac, any project after the first one fails to be migrated. It also appears that no new issues can be created (issues/add page produces 'internal error.') Upon further investigation, both problems appear to be related with the primary key sequences: after the import, the primary key sequence is not reset, and the next object that is created will try to use a duplicate primary key value.

This occurs in a setup using Postgres. I have not tested with any other databases, so it's possible that this problem is particular to Postgres.
