Yes, the current implementation of Slony needs a letter for each 
column telling it whether it's a key or a value. If you don't have 
enough letters in the argument, at best it will be missing columns in 
the update, at worst it will segfault. I sent a patch a while ago 
that allows you to add columns without having to update the trigger 
arguments, you should be able to find in the archives.
