BigInt validation uses incorrect limits and fails erroneously

[davismattg]

I have a column file_size on my Attachment model that is a bigint. When performing validation, any files that are larger than 2147483648 are failing since the schema validation treats that column as an Integer instead of using the size range for ActiveRecord::Type::BigInteger.

Are there any known workarounds for this? Currently I have just excluded that column with schema_validations except: :file_size but would prefer to keep the full schema_validations on that model. Thanks!
