Debug printouts are added at two locations: * Inside `get_foreign_upper_paths` a notice with the existing paths is send back together with the stage if the `show_upper` is set to show the stage. * Inside `set_rel_pathlist` a notice is printed with the existing paths if the `show_rel` debug flag is set. The debug printouts are sent back to the client as debug messages (`DEBUG2`), allowing developers to quickly experiment and interactively see what effect different statements has with the respect to the paths generated. In addition, the handling of `debug_optimizer_flag` was not correct and is fixed here. * If no `=` was provided to `show_upper`, it triggered a segmentation fault. * If the flag was reset, the internal data structure was not updated. * If just one flag was updated in a `SET` command, the other flag was kept intact.
