In initdb, defend against assignment of NULL values to not-null columns.
Previously, you could write _null_ in a BKI DATA line for a column that's
supposed to be NOT NULL and initdb would let it pass, probably breaking
subsequent accesses to the row. No doubt the original coding overlooked
this simple sanity check because in the beginning we didn't have any way
to mark catalog columns NOT NULL at initdb time.
