I'm not really sure about that one way or the other.  Our policy on
which configurations are supported vis-a-vis 'make installcheck' seems
to be, essentially, that if a sufficiently-prominent community member
cares about it, then it ends up getting made to work, unless an
even-more-prominent community member objects.  That's why, for
example, our regression tests pass in Czech.  I can't begin to guess
whether breaking installcheck against configurations with low values
of max_parallel_workers or max_worker_processes will bother anybody.
