Specify an alternate column type. This is possibly specific to the database
engine. By default the engine picks the type based on the field type. This
only has any bearing when creating tables.
This does NOT affect parameter types, and should still be something that
properly serializes to/from the given D type. For example, a string field
could be adjusted to be VARCHAR(10) instead of TEXT. Use a specialized type
to convert between different D types.
