Unfortunately it affects ALTER cases as well. And there is nothing
pgAdmin even _could_ do about that.
Say, a user has CREATE rights on tablespace foo. He moves a table
there (or creates it there).
ALTER TABLE test SET TABLESPACE foo;

But later he is unhappy with the results. So he tries to move it back
where it came from: to pg_default, but he cannot!
ALTER TABLE test SET TABLESPACE pg_default;

In my book that's listed under "postgres bug", not under "sane". In
practice an admin has to explicitly grant CREATE rights on pg_default
along with any CREATE rights on any tablespace, or it will be a one
way trip. How many admins would think of that or even know it?
