Test case:

create table t ();
create table t_1 () inherits (t);
create table t_2 () inherits (t);
create table d () inherits (t_1, t_2);

\d+ t
\d+ d

                 Table "public.t"
 Column | Type | Modifiers | Storage | Description=20
--------+------+-----------+---------+-------------
Child tables: t_1,
              t_2
Has OIDs: no

                 Table "public.d"
 Column | Type | Modifiers | Storage | Description=20
--------+------+-----------+---------+-------------
Inherits: t_1,
          t_2
Has OIDs: no

English, correct indentation:
. . .
Child tables: t_1,
              t_2
. . .
Inherits: t_1,
          t_2

Russian (UTF-8), wrong indentation:
