Or implementing it by keeping all data in the table in which it
was declared. (I.e., supertable holds all rows; subtable holds
only the primary key and those columns of the row that are not
in the supertable.)

From looking at the various discussions of this in books, and what
it appears to me that the SQL standard says, it seems that their
overall vision of table inheritance is to be consistent with the
implementation that I described above.
