Show method of index

Hi,

I think that can be useful the command \di on psql show the method of
index (hash, btree, ...) like:

test=# \di
List of relations
Schema | Name | Type | Owner | Table | Method
--------+---------------+-------+------------+--------+--------
public | test_id_idx | index | postgresql | table1 | btree
public | test_name_idx | index | postgresql | table1 | hash
(2 rows)

Or maybe only on \di+.

test=# \di+ test_id_idx
List of relations
Schema | Name | Type | Owner | Table | Method |
Size | Description

--------+-------------+-------+------------+--------+--------+------------+-------------
public | test_id_idx | index | postgresql | table1 | btree | 8192
bytes |
(1 row)

If they wanna, i can submit the patch of this small change of psql.
