Now that we have a more-or-less full set of buildfarm results
on this, I checked for new warnings, and found two:
pg_shmem.c: In function 'PGSharedMemoryIsInUse':
pg_shmem.c:323:33: warning: passing argument 1 of 'shmdt' from incompatible
pointer type [-Wincompatible-pointer-types]
323 | if (memAddress && shmdt(memAddress) < 0)
| ^~~~~~~~~~

| PGShmemHeader *
In file included from pg_shmem.c:27:
/usr/include/sys/shm.h:131:11: note: expected 'char *' but argument is of type
'PGShmemHeader *'
131 | int shmdt(char *);
| ^~~~~~
pg_shmem.c: In function 'PGSharedMemoryCreate':
pg_shmem.c:838:37: warning: passing argument 1 of 'shmdt' from incompatible
pointer type [-Wincompatible-pointer-types]
838 | if (oldhdr && shmdt(oldhdr) < 0)

This is from hake[1], which is running OpenIndiana/illumos.
That platform shows a couple of other strange warnings, so maybe
re-eliminating these two is not worth worrying about, but
nonetheless the casts to void * were doing something here.
