GiST future

Hi every one.

I've played a bit with contrib/intarray and very much liked being able to
index a whole array.

Now I wonder why 7.4 array queries using SOME/ANY/ALL don't make use of
this king of indexes.

Is there any plan to integrate Oleg's job into the core as GiST indexes
were?

it would be nice to generalize things like
SELECT col1 from table where col2 contains (select col3 from table2 where
...) and use those indexes.

Or did I miss something in the docs?

What does core team think?

Best regards
