  Unless the table has had a column added with ALTER TABLE.  In that
  case, the column doesn't exist in the on-disk record of the row.  The
  SELECT knows it doesn't have enough columns, so it figure out what
  the default value for that column should be and silently adds it
  without altering the original record.
