pg_lscluster is great, but it's Debian/Ubuntu specific.
$ realfs=$(df -x tmpfs -x devtmpfs | tail -n +2 | awk '{print $6;}' | xargs)
$ find ${realfs} -xdev -type f -name pg_ctl |& grep -v "Permission denied"
This works on both Ubuntu 18.04 and RHEL 8.3 (the only systems I have access
to), but wonder if there's a Better Way. (I didn't grep netstat because
the cluster might not be running.)
Thanks
