They're the same but the interpretations are different, which is why
I think it's useful to have two typedefs as a way of documenting what
any given value is intended to be.  The argument for having a third
typedef would be exactly the same: to help document what a value is
intended to be.

       choose an index scan if your joining column's datatypes do not
       match
