The schema dumper would dump out any decimal or numeric column that had a zero
scale as an integer column. This will cause problems for very large precision
columns on some DBMSs, particularly PostgreSQL. It also looks strange to see
your column change type after moving through schema.rb.

The FlashHash and friends causes a lot of needless session storing, when we know for a fact that there's no content in the flash. By not storing the empty hash in the session we save a lot of communication with the various session backends, while still keeping the same interface to the flash. [#2703 state:resolved]
