That makes more sense, though isn't that a little repetitive when
"default nextval(...)" is visible immediately above it?

Doesn't guarantee the sequence is owned by the table of course, but I'd
imagine to most people it'd just be noise.  Could see it being shown in
the verbose version, \d+ foo.bar.

I certainly like that better than "making up" an nonexistent column. :)

For the sequences themselves, it'd be nice to show somewhere, at least
for tracking down stray sequences and identifying relationships.
Perhaps a function to do the reverse of pg_get_serial_sequence()?  Or
better yet if no one else is already working on it, a more generic way
to get readable information out of pg_depend?
