So the problem is that we do this:

./pgbench -c4 -j2 -t 10 -n -M prepared -f /home/alvherre/Code/pgsql-build/REL_16_STABLE/src/bin/pgbench/tmp_check/t_001_pgbench_with_server_main_data/001_pgbench_pipeline

and get this error:
pgbench: error: threads are not supported on this platform; use -j1

So, the fix is just to remove the -j2 in the command line.  I'll do that
in a jiffy.  There's no other test that uses -j, except the one
specifically designed to test threads.
