You need to modify all the table and sequence OIDs stored in the slony 
configuration tables to reflect the new table and sequence OIDs.

You need to update the slony functions through the appropriate slon 
commands.

There may also be other problems; it's not really a supported operation, as 
I understand it, and it's been a while since I've personally done it.
