Well, here's your flaw: If you expect the data dumper to be able to
export the rows, then the system must know that the rows/tables are
there, and thus cannot be "hidden" for any definition of hidden. To
find them, you just do the work that the dumper would do.
Ie, you seem to want to be able to write files that postgres doesn't
know are there, and that I don't believe you can do.
