Hi Andres,

In my work on more careful PostgreSQL resource management, I've come to the
conclusion that we should avoid pushing policy too deeply into the
PostgreSQL core itself. Therefore, I'm quite skeptical about integrating
NUMA-specific management directly into core PostgreSQL in such a way.
I think it's actually the opposite - whenever we pushed stuff like this
outside of core it has hurt postgres substantially. Not having replication in
core was a huge mistake. Not having HA management in core is probably the
biggest current adoption hurdle for postgres.
To deal better with NUMA we need to improve memory placement and various
algorithms, in an interrelated way - that's pretty much impossible to do
outside of core.
Except the backend pinning which is easy to achieve, thus my comment on
the related patch.
I'm not claiming NUMA memory and all should be managed outside of core
(though I didn't read other patches yet).
