Description:

Hi.

On https://www.postgresql.org/docs/12/kernel-resources.html, the command to
calculate memory allocated to postgres is not correct. Following is the
command as shown in 18.4.5. Linux Huge Pages.

pmap 4170 | awk '/rw-s/ && /zero/ {print $2}', this command does not return
any results with correct pid. Probably /zero/ needs to be updated with
/anon_hugepage/

Thanks,
Sanjeev Adwal
