Create a reverse-LIKE operator and underlying one-line SQL function.

Thanks Tom.
For the benefit of future searches I used:
create function reverse_ilike(text, text) RETURNS boolean AS 'select $2 ilike $1;' LANGUAGE SQL IMMUTABLE RETURNS NULL ON NULL INPUT;
create operator ~~*^ (PROCEDURE = reverse_ilike, LEFTARG = text, RIGHTARG = text);
Best,
Rusty
