Even for a char(4) field? ok, if attlen doesn't give the
length of a field, how do I find it?
Right now: yes, but I would like to see the char() type changed to a fixed length type (which it really is)
then it would have the length in attlen. Right now the length for char and varchar is in atttypmod.
