Primary Key on Inherited Table

Hi,

I was trying to create a table that inherites from a parent table. I have
to use the fields both from the parent table and the child table to define
the primary key. Unfortunately I was not able to do that. It can not find
the fields from the parent table and give me the error "column .. does not
exist". I can not specify the fields by using parenttable.column either. I
have read the documentations and there is nothing in the inheritance chapter
talking about primary key. Is there a way to specify primary key in the
child table using columns from parent table? I am using 6.5.0. Helps will
be greatly appreciated.
