There's a related issue: what about the table's TOAST table (if any)
and the index on same?

During CREATE TABLE, the toast table is assigned to the same tablespace
as the base table, as is its index. I don't think this is wrong exactly
--- the fact that we separate data storage into main and toast tables is
an implementation detail that users shouldn't have to think about.

If you subscribe to that notion, then ALTER TABLE SET TABLESPACE had
better move the toast table and index too. If you don't subscribe
to it, then ALTER TABLE SET TABLESPACE had better be able to move
toast tables, and the issue will have to be documented.
