Обсуждение: Handling case variatiions on a user defined type?

I have several enumerated types that look like:

CREATE TYPE confidence_level AS ENUM ('HIGH' ,
                                'MEDIUM' ,
                                'LOW' ,
                                 'WAG');


I have someone creating data for this project in spreadsheets, and then am
importing the data using \copy.

Problem is the data in the spreadsheets is entered in mixed case.

Is there a way that I can use the type itself, to enforce something like a
to_upper(). Or is there a better way to  "human proof" this?

That sounds like a good idea, thanks.
