ooh. good point. What would be a good operator for that?
I'm thinking that (hstore -> text[]) should probably return text[],
and maybe (hstore => text[]) returning hstore?
i.e.
select ('a=>1,b=>2,c=>3'::hstore) -> ARRAY['a','b'];
-- returns '{1,2}'
select ('a=>1,b=>2,c=>3'::hstore) => ARRAY['a','b'];
-- returns 'a=>1,b=>2'
(by analogy to the existing operators -> for lookup and => for
construction)
