<div class="block">Return true if the this class' primary key columns correspond to the
base class' primary key columns used to construct oid values. Base
classes always return true. Classes that join to the base class table,
though, may not always join using the same columns the base class
uses for oid values, or may not use all the columns. When performing a
select, we will join down to the most-derived class that is identified
by oid values. We cannot use non-primary key field values for joining
during selects, because the field values to join on might be the ones
we're trying to select! Similarly, we can only reconstruct oid values
for selected objects using classes whose primary keys store oid values.</div>
