something wrong when using xorm reverse on unique index

error message

[Error] reverse.go:178 Unknown col is_default) WHERE in index userc_addr_userc_id_is_default_key of table userc_addr, columns [id userc_id name phone city area detail is_default create_time area_id city_id]

the table

create table userc_addr(
  id bigserial primary key,
  userc_id bigint REFERENCES userc(id),
  name varchar(128),
  phone varchar(11),
  city varchar(128),
  area varchar(128),
  detail text,
  is_default boolean DEFAULT FALSE,
  create_time timestamp with time zone,
  area_id int,
  city_id int
);
CREATE UNIQUE index userc_addr_userc_id_is_default_key on userc_addr(userc_id, is_default) where is_default=true;
CREATE index userc_addr_userc_id_idx on userc_addr(userc_id);

the sql of userc table

create table userc(
  id bigserial primary key,
  phone varchar(11),
  create_time timestamp with time zone,
  UNIQUE(phone)
);

I think the problem is here.

cs := strings.Split(indexdef, "(")
colNames = strings.Split(cs[1][0:len(cs[1])-1], ",")

when execute
SELECT indexname, indexdef FROM pg_indexes WHERE tablename='userc_addr' and schemaname='public';
got indexdef
CREATE UNIQUE INDEX userc_addr_userc_id_is_default_key ON public.userc_addr USING btree (userc_id, is_default) WHERE (is_default = true)

I can submit a pull request if necessary.
