As far as I can tell, SEMVMX isn't readable or writable via /proc or
sysctl in Linux at all; at least it is not visible in my Red Hat 8.0
installation. So it's really hard to see why it'd be different in
your installation than everywhere else.

Just to make sure we're barking up the right tree, would you see whether
it helps to change this line in src/backend/port/sysv_sema.c:

#define PGSemaMagic 537 /* must be less than SEMVMX */

Try making it 100 or so instead of 537.
