pgsql: Fix ALTER TABLE to check pre-existing NOT NULL constraints when

Log Message:
-----------
Fix ALTER TABLE to check pre-existing NOT NULL constraints when rewriting
a table.  Otherwise a USING clause that yields NULL can leave the table
violating its constraint (possibly there are other cases too).  Per report
from Alexander Pravking.
