It's not a good design to use INTS when TINY/SMALL work, so how do you allow Sequelize models to express this but still work on other databases? Just some questions I had while using the ORM. But should these things be handled transparently, automatically converted, best guessing? Should Sequelize itself deny invalid model attributes on its sync, before it hits the database? The same can be said about Mysql's INT sub-types, such as MEDIUMINT. I understand Sequelize is an ORM, not a database abstraction library. And the later is documented, but I don't think it's simple a matter of documenting about sqlite UNSIGNED, because of the philosophical issue. You can't UNSIGNED a sqlite column, and you also can not ARRAY a non-Postgres column. The practical is that Sequelize allows a certain combination of modeling that does not work, it generates invalid sql statements. But I think there are two issues here, one practical and one philosophical.
