Hash opclass is 5-times simpler that btree one :)
CREATE FUNCTION citext_hash(mchar)
RETURNS int4
AS 'MODULE_PATHNAME'
LANGUAGE C IMMUTABLE RETURNS NULL ON NULL INPUT;
CREATE OPERATOR CLASS citext_ops
DEFAULT FOR TYPE mchar USING hash AS
OPERATOR 1 = (citext, citext),
FUNCTION 1 citext_hash(citext);
