FWIW "psql db -f src/test/regress/sql/join_hash.sql | cat" also works (I mean, it's self-contained and doesn't need anything else from make check; pipe to cat just disables the pager); that's how I've been trying (and failing) to reproduce this on various computers. I also did a lot of "make -C src/test/module/test_shm_mq installcheck" loops, at the same time, because that's where my animal hung.
