Ah, good idea. Updated patch attached. The output is now:

test=> \d+ test
Table "public.test"
Column | Type | Modifiers | Storage | Stats target | Description
--------+---------+-----------+---------+--------------+-------------
x | integer | not null | plain | |
Indexes:
"test_pkey" PRIMARY KEY, btree (x) REPLICA IDENTITY
"i_test2" btree (x)
--> Replica Identity: USING INDEX "test_pkey"
Has OIDs: no

However, now that I look at it, it seems redundant as REPLICA IDENTITY
is already marked on the actual index. Ideas?
