lsm3 index bloat?

[digoal]

HI, lsm3 index more larger than btree index:

postgres=# create index idx on t using lsm3(id) with (unique=true);
postgres=# insert into t select generate_series(1,10000000), md5(random()::text);

postgres=# \dt+ t
                           List of relations
 Schema | Name | Type  |  Owner   | Persistence |  Size  | Description 
--------+------+-------+----------+-------------+--------+-------------
 public | t    | table | postgres | permanent   | 651 MB | 

 public | idx              | index | postgres | t           | permanent   | 69 GB      |
