Okay, so the question is what tablefunc wants to do. I'd guess it
wants to duplicate the set of info returned by SHOW ALL.

I put in GUC_NO_SHOW_ALL when I was hacking on GUC a few months ago
to make it able to implement the last few SET variables that had
one-of-a-kind behavior. One of those one-of-a-kind behaviors was that
some of them didn't show up in SHOW ALL. I suppose this is arguably
a bug and not really behavior we want to preserve --- although SHOW SEED
will *never* return anything useful and so it's not clear why SHOW ALL
should bother to show it.
If NO_SHOW_ALL bothers you, feel free to put its removal up to a
pghackers vote. I'm not wedded to it.
