Works on this Postgres 17.7:

postgres=# show server_version; server_version ------------------------------- 17.7 (Debian 17.7-3.pgdg13+1) (1 row)

postgres=# SELECT sum(blks_hit)/nullif(sum(blks_hit+blks_read),0) AS cache_hit_ratio FROM Pg_stat_database; cache_hit_ratio ------------------------ 0.99448341937558994728 (1 row)

Yes. And that was 4 years ago. Must add that figure does NOT include static asset serving path.

They do. Here's my shell function that helps me switch between DisplayPort-1 + USB uplink cable to the host AND USB-C cable with DisplayPort Alt Mode+Charging+uplink to display's USB hub.

  # x0f: DisplayPort-1
  # x1b: USB-C
  DDC_SOURCES=("x0f" "x1b")

  switchkvm() {
    local vcp_input_src="x60"
    local current next src
    current=$(ddcutil -t getvcp ${vcp_input_src} | awk '{ print $4 }')
    for src in "${DDC_SOURCES[@]}"; do
      if [[ ${src} != "${current}" ]]; then
        next=${src}
      fi
    done
  
    if [[ -z ${next} ]]; then
      echo "No eligible alternate input in \$DDC_SOURCES" >&2
      echo "\$DDC_SOURCES=(${DDC_SOURCES[*]}); current=${current}"
      return 1
    fi

    ddcutil setvcp "${vcp_input_src}" "${next}"
  }

Dunno. This works for me without damaging the parts, pads, or traces. Your link is for PCBA reflow ovens. Talks about minutes long of exposure. I'm using a Atten ST-862D hot air station with questionable temperature and airflow accuracy. For an M.2 drive I'll probably soak 225 for 15 seconds 3 times the size of the chip areas in circles. Hit my memory-1 button to go to 400 and focus on the chip for 3 seconds. Hit memory-2 to go down to 300 and one up arrow for 325 for 5 more seconds while watching nearby caps' solder pads and ensuring they don't fly away. ¯\_(ツ)_/¯

Reflowing the controller worked for me twice for now. Once with an Intel Optane drive that worked without issues for 3 years and started overheating one day. And another one from a fanless machine that used an mSATA drive that chose to die on a Sunday, with no spare mSATA disk lying around. In both cases I went for short hunting under a microscope, looking for that one guilty shorted cap, yet finding none. It was the controllers with "tired" BGA solder balls, which could use some tender loving care of 225°C (soak) -> 400°C (peak) -> 325°C (hold) reflow.

Katriel Cohn-Gordon is also a Meta employee.

Seems like only available in certain locations.

You can play with the `gl` query parameter in the URL. Yours is for Italy ("it"). It's available in other continental Europe locations like: de, fr, be, es, pt, at, cz, pl. While not yet released for majority English speaking countries (us, ca, uk, au, nz) with the exception of Ireland (ie).

I don't have any insider information even though my employer is Meta. I learned about this release from HN.

Tangent: U.FL connectors. Gawd, they suck. I was pleasantly surprised to see U.FL removal tool in the write up. The female connectors have at best 10 mating cycles in my experience. By using the such removal tool you may get dunno 20 if you are super careful. I killed GSM and GPS antennas with single or second try detaching.

From wikipedia article of Hirose U.FL:

Female U.FL connectors are not designed with reconnection in mind, and they are only rated for a few reconnects (approximately 30 mating cycles[5]) before replacement is needed.
