I would like to be able to redefine a field in a table to be a foreign 
reference -- however this field was initially defined as just "serial" and 
not "serial primary key".  I tried to add that constraint to the table, but 
it didn't work.  Do I need to copy out the table, drop it, and recreate it 
with this constraint in order for it to be a foreign key?
