Description

When submitting a review on a pull request I get an Error 500 page. It seem the text you enter when approving or rejecting a PR is only intended to be rather short, and therefore the database column review.content is limited to 255 characters. However the user interface doesn't restrict the input to this limit.

Change it's tag to TEXT and add a migration will fix that.
