TypeError: can't set attributes of built-in/extension type 'asyncpg.Record'

Hi, I am trying to monkey patch the Record class (the getter) to get an history of every column that got accessed in the record (to only query what the user really need for the next n queries). However I cant do that, I got the error of the title.

I am pretty sure this is related to #451 and the strange nature of Record object.

I would like to know why Records are made like that and if you will change that. Right now I think I will re implement my driver class with another library if you dont have any workaround

The records are made to mimic Python tuple design to achieve the best performance possible. I don't think we can allow monkey patching it, but we should allow users to provide their own factory for custom records. That will solve your use case, although i have no eta.

You can of course work on a PR for that.
