Disallow NAMEDTUPLESTORE RTEs in stored views, rules, etc.

A named tuplestore is necessarily a transient object, so it makes
no sense to reference one in a persistent object such as a view.
We didn't previously prevent that, with the result that if you
tried you would get some weird failure about how the executor
couldn't find the tuplestore.

We can mechanize a check for this case cheaply by making dependency
extraction complain if it comes across such an RTE.  This is a
plausible way of dealing with it since part of the problem is that we
have no way to make a pg_depend representation of a named tuplestore.

Report and fix by Yugo Nagata.  Although this is an old problem,
it's a very weird corner case and there have been no reports from
end users.  So it seems sufficient to fix it in master.
