"Usage: uninstall_nodes [--config file]
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.
