Again, we can do this, but we then have to have atttypmod available in
all places where we check for length.  I will add it to the TODO list.

I am starting to see the problem, only atttypmod is passed around not attlen.
Therefore even if we do this, the char() length of a column still has to be in atttypmod.
So it will stay the same for Julie, whether it is taken out or not. But since it is really 
hard for a generic application like ODBC, maybe we could change atttypmod to not 
include the VARHDRSZ, most of the time it is needed without VARHDRSZ anyway ?
I am starting to think that this would be more important than to remove the 4 bytes.
