It was an idea. I think I will remove it from the TODO list. I had
considered it so I could save the defined length(atttypmod now) in
there, but now that we have atttypmod, we don't need it. It will stay
at 4 bytes.

Ooh, this is interesting. Yea, I guess we really don't need that for
char() anymore. The only problem is that we would have to do some fancy
stuff to track char() separately in the backend, and I am sure atttypmod
is not available in all the places we need it. Don't think it is worth
it.

Hmmm.
