using slony with pgadmin

I need to replicate a database using slony that has tables created in it from 
pgadmin.  I've hit a snag because slony requires that all replicated tables 
have a primary key, and the pgadmin tables dont have one.  Basically I am 
wondering if anyone has replicated pgadmin tables with slony, or barring that 
if anyone has any suggestions on how I should go about adding primary keys to 
the pgadmin tables so as not to break anything.  Thanks in advance.
