Something has happened in this area in the shape of 96cdeae, and the
following catalogs do not have toast tables: pg_class, pg_index,
pg_attribute and pg_largeobject*. While 0001 proposed upthread is not
really relevant anymore because there is already a test to list which
catalogs do not have a toast table. For 0002, indeed the patch is still
seems relevant. The comment block at the beginning of
create_toast_table should be updated. Some tests would also be nice to
have.
