And that is not even the tip of the iceberg.  The real reason that NAME
is fixed-length is so that it can be accessed as a member of a C
structure.  Moving NAME into the variable-length category would make it
much more painful to access than it is now, and would require
rearranging the field order in every system catalog that has a name field.
