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.
