I don't know what numactl does, so I cannot comment on whether it's a
good idea to do this, and whether it's always safe to do.

However, if you want to apply this, you need to check whether numactl
is actually available. Preferably, call `which numactl` and use that
path, and if that fails don't use it at all. It's in the "numactl"
package which isn't installed by default.

A more generic approach which would also allow strace, gdb, etc. is to
add a new option --pg-ctl-prefix or environment variable
$PG_CTL_PREFIX?

Thanks,

Martin
