Comment(by strk):

 The exception comes from the attempt to drop the registered (but missing)
 layers:
 {{{
 NOTICE:  Dropping all layers from topology topo_235bis (1295)
 ERROR:  relation "topo_235bis.relation" does not exist
 LINE 1: DELETE FROM topo_235bis.relation  WHERE layer_id = 1
                     ^
 QUERY:  DELETE FROM topo_235bis.relation  WHERE layer_id = 1
