The latest patch looks good to me apart from one Debug message, so I
have marked it as Ready For Committer.
+ ereport(DEBUG1,
+ (errmsg("disabling huge pages")));
I think this should be similar to what we display in sysv_shmem.c as below:
elog(DEBUG1, "mmap(%zu) with MAP_HUGETLB failed, huge pages disabled: %m",
allocsize);
