Hi,
 
I am trying to generate some xml metadata from the pg system tables for my java code generation utility. I have can get most information, but i would like to be able to tell which column is a primary key or which one is a foreign key (i dont need to know which table the foreign key references at this point).
 
Which tables do i need reference, could anyone provide an example query?
