Yes, I noticed it too.

Should we use your get_index_isclustered more widely ?

Also, should we call it "is_index_clustered", since otherwise it sounds alot
like "+get_index_clustered" (without "is"), which sounds like it takes a table
and returns which index is clustered.  That might be just as useful for some of
these callers.
