Hmm, that does mention setproctitle, and our ps_status.c does indeed
clobber some stuff in that region (in fact our ps_status.c is likely
derived from the setproctitle() function from sendmail AFAICT).  But
that's in our "backend" server processes, unlike the problems we have
on Macs... oh but you're failing to load libpqwalreceiver.so which
makes some sense for the backend hypothesis.  What happens if you hack
ps_status.c to use PS_USE_NONE?
