Well, the reason that way seemed like a kluge is that I don't see what
connection is_alter_table has to overriding DefineIndex's normal idea
of which tablespace to use. I think that's at least as likely to
induce new bugs as fix them. For instance, wouldn't it change the
behavior of ALTER TABLE ADD PRIMARY KEY? It seems to me that that
command *should* honor default_tablespace, if there's no tablespace
clause in it.
