RE: Problems with ever-increasing ID value

I don’t know if there’s a rails-specific answer to this or not, but
that’s a property of the underlying database, not rails. In general,
IDENTITY columns get auto_incremented, and id #s will not be re-used
unless the table is specifically re-seeded. Check the documentation for
your DB and see how to re-seed the identity column for that table.

Hope that helps
