bug report: pgadmin 1.20.0 Windows 8.1 MATERIALIZED VIEW with INDEX, pgadmin doesn't show the INDEX

For example:

set search_path = scratch;

drop materialized view if exists temp_a;

create materialized view temp_a as
select version() as str;

create index on temp_a (str);

select *
from temp_a;

Data Output:
str text
PostgreSQL 9.3.9 on x86_64-unknown-linux-gnu, compiled by gcc
(Ubuntu/Linaro 4.6.3-1ubuntu5) 4.6.3, 64-bit

In the SQL pane I don't see the index, and they aren't in the Object
browser either:

-- Materialized View: scratch.temp_a

-- DROP MATERIALIZED VIEW scratch.temp_a;

CREATE MATERIALIZED VIEW scratch.temp_a AS
SELECT version() AS str
WITH DATA;

ALTER TABLE scratch.temp_a
OWNER TO xxx;
