Although you only see the effects in pg_dump, this is actually a backend
problem (pg_dump depends on pg_get_viewdef(), which wasn't being careful
about this situation).

I've committed fixes into current CVS for this, but I don't think there
will be a back-patch for 7.2 ... the risk of breaking other cases is
too high to put it out without a normal beta-test cycle.
