You started out okay with your test script, but the pg_depend bit needs
work. I would recommend examining that table closely until you have a
really good understanding of how it works - both on the objid and refobjid
side. Create and modify tables and see how the pg_depend entries change.
Hint: Try it with and without foreign keys.

Yes, as I mentioned upthread, the safest thing will probably be a restart.
Cheers,
