Overview

Do not use ActiveRecord::ModelSchema.reset_column_information in migrations. The method is not thread safe and we run migrations concurrently for multisites. Also, we don't encourage the use of ActiveRecord methods in migrations and prefer to write SQL directly.

"method also means ActiveRecord methods are being used in migration " \
"which is discouraged at Discourse. Instead, you should write SQL in your migrations instead."
