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

A table can only have ONE primary key. 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.
