... except it doesn't make a lot of sense to have set_rel_tablespace in
either indexcmds.c or index.c. I think tablecmds.c is a better place
for it. (I would have thought catalog/storage.c, but that one's not the
right abstraction level it seems.)
But surely ATExecSetTableSpaceNoStorage should be using this new
routine. (I first thought 0002 was doing that, since that commit is
calling itself a "refactoring", but now that I look closer, it's not.)
