Re: remaining sql/json patches

Also FYI - the following case results in segmentation fault:

postgres@postgres=# CREATE TABLE test_jsonb_constraints (
        js text,
        i int,
        x jsonb DEFAULT JSON_QUERY(jsonb '[1,2]', '$[*]' WITH WRAPPER)
        CONSTRAINT test_jsonb_constraint1
                CHECK (js IS JSON)
        CONSTRAINT test_jsonb_constraint5
                CHECK (JSON_QUERY(js::jsonb, '$.mm' RETURNING char(5) OMIT QUOTES EMPTY ARRAY ON EMPTY) >  'a' COLLATE "C")
        CONSTRAINT test_jsonb_constraint6
                CHECK (JSON_EXISTS(js::jsonb, 'strict $.a' RETURNING int TRUE ON ERROR) < 2)
);
CREATE TABLE
