Depends where you got the tupleDesc from --- if you copy it into the
parse context then it's OK in terms of not disappearing.  However,
that doesn't mean it's still *valid*.  Consider

	begin;
	declare foo cursor for select * from bar;
	create view v1 as select * from cursor foo;
	end;

Now the cursor foo is no more, but v1 still exists ... what happens
when we try to select from v1?
