Woah.  This one is old, good catch from -DRELCACHE_FORCE_RELEASE.  It
happens that since its introduction in a3519a2 from 2002,
currtid_for_view() in tid.c closes the view and then looks at a RTE
from it.  I have reproduced the issue and the patch attached takes
care of the problem.  Would it be better to backpatch all the way down
or is that not worth caring about?
