Hi Jonathan,

> Finally, PostgreSQL 18 introduces support for [NUMA awareness](https://www.postgresql.org/docs/18/install-make.html#CONFIGURE-OPTION-WITH-LIBNUMA) that adds basic [NUMA observability](https://www.postgresql.org/docs/18/view-pg-shmem-allocations-numa.html) to PostgreSQL.

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)
