Shameless plug: maybe the LISTEN/NOTIFY optimization could be added?

The work to fix the problem was triggered when I saw the

"Postgres LISTEN/NOTIFY does not scale"

article posted on Hacker News front-page [1] [2].

If of interest, maybe plug in this sentence

"better LISTEN/NOTIFY scalability for multi-channel workloads"

at the end of the ### Performance paragraph that begins with:
"PostgreSQL 19 shows up"?
