can't see operator classes

i use pgAdminIII (Win32 binary) version 1.4.3 to test my relational DB
running on Postgresql v8.1.3.

For some indexes i use operator classes such as varchar_pattern_ops
for LIKE selections. but i cant see the operator class definition in
pgAdmin table "properties". They are seen in dumps that i have created
with pg_dump.

ex:

dump file segment created by pg_dump for index__xxx_yyy
--------------------------------------------
CREATE UNIQUE INDEX index__xxx_yyy ON xxx USING btree (yyy varchar_pattern_ops);

pgAdmin properties section for index__xxx__yyy
----------------------------------------
CREATE UNIQUE INDEX index__xxx__yyy
ON xxx
USING btree
(yyy);

is there a way to see such operator classes?

advTHANKSance
