We have one opclass for each type combination -- int4 to int2, int4 to int4, int4 to int8, etc. You just need to add the new strategy to all the opclasses. BTW now that we've gone through this a little further, it's starting to look like a mistake to me to use the same @> operator for (anyarray, anyelement) than we use for (anyarray, anyarray). I have the feeling we'd do better by having some other operator for this purpose -- dunno, maybe @>> or @>. ... whatever you think is reasonable and not already in use.
