    Removes Slony configuration from all nodes in a cluster.

Restores all tables to the unlocked state, with all original user       
triggers, constraints and rules, eventually added Slony-I specific      
serial key columns dropped and the Slony-I schema dropped. The node     
becomes a standalone database. The data is left untouched.              
 
The difference between UNINSTALL NODE and DROP NODE is that all         
UNINSTALL NODE does is to remove the Slony-I configuration; it doesn't  
drop the node's configuration from replication.
