DBIx::Class is much nicer for this. It supports schema versioning and
automatic deployment to any supported database (SQLite, MySQL, Postgres, SQL
Server, Sybase, DB2, and Oracle). I can expand on this, but the DBIx::Class
docs are pretty good and #dbix-class will probably help you with anything you
need.
The only disadvantage is that version information is stored out-of-band on the
filesystem, not in the database.
