    declare
    	p_set_id			alias for $1;
    	v_origin			int4;
    begin
    	-- ----
    	-- Grab the central configuration lock
    	-- ----
    	lock table sl_config_lock;

    	-- ----
    	-- Check that the set exists and originates here
    	-- ----
    	select set_origin into v_origin from sl_set
    			where set_id = p_set_id;
    	if not found then
    		raise exception 'Slony-I: set % not found', p_set_id;
    	end if;
    	if v_origin != getLocalNodeId('_schemadoc') then
    		raise exception 'Slony-I: set % does not originate on local node',
    				p_set_id;
    	end if;

    	-- ----
    	-- Call the internal drop set functionality and generate the event
    	-- ----
    	perform dropSet_int(p_set_id);
    	return  createEvent('_schemadoc', 'DROP_SET',
    			p_set_id);
