The only scenario where this would be useful is when using ALTER TABLE
ADD CONSTRAINT in which case a fresh index is built (not USING INDEX).
That's a bit narrow, because it would mean that you would either
append a TABLESPACE clause to this existing clause, or create a
storage parameter to enforce all indexes created for a relation on a
wanted tablespace... For the other cases you could just do something
like that, and that's what the large majority of people would care
SET default_tablespace TO 'foo';
CREATE TABLE foobar (id int PRIMARY KEY);
But that's not the one you are interesting in, so likely a storage
parameter is what pops up in my mind, with parameter defined at table
creation: CREATE TABLE foo (id primary key) WITH
(constraint_default_tablespace = foo) TABLESPACE bar;
In this case the parent relation gets created in tablespace bar, but
its primary key gets in tablespace foo.
