This isn't a bug.  You need to double-quote the index name, just the same
as you would do at the SQL level.

regression=# create table unfindable("Test" text);
CREATE TABLE
regression=# create index on unfindable("Test");
CREATE INDEX
regression=# \d unfindable
 Table "public.unfindable"
 Column | Type | Modifiers
--------+------+-----------
 Test   | text |
Indexes:
    "unfindable_Test_idx" btree ("Test")

regression=# select pg_relation_size('unfindable_Test_idx');
ERROR:  relation "unfindable_test_idx" does not exist
LINE 1: select pg_relation_size('unfindable_Test_idx');
                                ^
regression=# select pg_relation_size('"unfindable_Test_idx"');
 pg_relation_size
