I'll work on a minimal CLUSTER testcase within the next day or two,
and post a revision. Separately, I'll propose a patch that further
expands tuplesort test coverage. This will add coverage for hash
tuplesorts, as well as coverage of external sorts that require
multiple passes.

Thanks for going to the trouble of confirming that the test procedure
causes a segmentation fault, and that my patch appears to fix the
issue.
