For some reason I find this sentence not accurate: NUMA awareness somehow indicates that we get performance benefits out of this, but we do not (yet*) - we simply provide some insight into NUMA memory layout so far and link against libnuma. So maybe we should remove "introduces support for [NUMA awareness](https://www.postgresql.org/docs/18/install-make.html#CONFIGURE-OPTION-WITH-LIBNUMA) that" and just leave it as "Finally, PostgreSQL 18 adds basic [NUMA observability]" ? Rationale: for every other software that I saw NUMA awareness reference was always linked to gaining performance , but just linking against libnuma is not giving us this. * = with on going work for 19 (future Tomas's we'll get there I hope) -J.
