> To change a column definition you have to manually update the underlying schema using the `writable_schema` pragma. If you mess this up you can be left with a corrupt database.

No you don’t [0]. It is less convenient than being able to directly alter columns, but you do not need to mess around with writable schemas or risk corruption.

I’m a bit confused. That’s not a column definition change, because the original column is the same, you’re doing a data migration. That is one way you would solve this class of problems in SQLite, but it’s a bit annoying compared to a something like `alter column`.
