Disallow NAMEDTUPLESTORE RTEs in stored views, rules, etc.

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.
