CLUSTER specified the wrong namespace when renaming toast tables of temporary

relations (they don't live in pg_toast).  This caused an Assert failure in
assert-enabled builds.  So far as I can see, in a non-assert build it would
only have messed up the checks for conflicting names, so a failure would be
quite improbable but perhaps not impossible.
