How do you select these sub Primary Keys? I tried using Shift-Select, Ctrl_Selec, but doesn't work. Thanks Sangeetha

It can have additional indexes with a UNIQUE restriction, thereby forcing the second field to be as good as a primary key. That is probably what you are looking for, however, you can also in PG Admin II select multiple fields as being the member of the primary key.
