pgAdmin 3 index display problem

Hello I'm getting into strange problem with pgAdmin 3.
As we all know, PostgreSQL enforces index creation on primary key's.
The problem with this is the fact, that when i create a table in pgAdmin's
sql editor, in result window i'm getting success and a note that an index
will be created on tables pripamary key - problem, when I am browsing
through table structure in my public schema, under newly created table in
index section there are no indexes until I create one explicitly.So does it
create an index?and it's pgAdmin's bug not displaying the auto created
index, or it works in such way - not displaying the auto index?

PostgreSQL version: 9.0.1
