"Usage: drop_set [--config file] set#
Drops a set.
Much as with DROP NODE, this leads to Slony-I dropping the Slony-I triggers on
the tables and restoring "native" triggers. One difference is that this takes
place on all nodes in the cluster, rather than on just one node. Another
difference is that this does not clear out the Slony-I cluster's namespace, as
there might be other sets being serviced.
This operation is quite a bit more dangerous than DROP NODE, as there isn't the
same sort of "failsafe." If you tell DROP SET to drop the wrong set, there
isn't anything to prevent potentially career-limiting "unfortunate results."
Handle with care...
