In `quickstart.sql` file the `name` column of `differential_diffproperty` table is `varchar(255)`, but in `DifferentialDiffProperty` it's set to `text128`. This results in schema warning immediately after clear Phabricator installation.
I think that all non-`Better Collation Available` (because these might add `utf8mb4` instead of `utf8_general_ci`, which might not be available for everybody) warning fixes should backported to the `quickstart.sql` as well.
