If you're suggesting that we should back-patch hstore 1.1 into 9.1,
there might not be a technical reason why we couldn't do it, but there
are certainly project-policy reasons. Removing operators, or indeed
changing any SQL interface at all, is exactly the kind of change we do
not make in back branches.

If the argument for this patch is only to support doing something like
the above, I'd vote for rejecting it entirely.
