I find it pretty odd to speculate that they are experiencing a very specific failure mode of a particular database. Do you even know whether they use Postgres?

Maybe their load balancer got hit by a 2009 Toyota Camry with a sticky accelerator pedal?

It is a very unlikely Y2K bug

I know we're already in the weeds, but Malcolm Gladwell’s “Revisionist History” did an excellent episode on the stuck accelerator problem, basically showing it almost certainly didn't happen.

It's not odd at all!

Speculation is a useful intellectual exercise, and the sign of a healthy, intelligent and curious mind!

Speculation is also fun!

No, it's just FUD directed at Postgres.

OP specifically pointed out that it's well documented. Every program makes tradeoffs, and I don't think anyone in this thread implied that because Postgres made this one it's unstable or bad.

The specific behavior of Postgres isn't the FUD, the FUD is the speculation that this is what brought down Roblox for multiple days. As others have mentioned, we don't even know if Roblox uses Postgres, and yet we're diving deep on how an edge case of Postgres brought down Roblox. It's the speculation that I think is FUD.

I did too but it's pretty easy to find out which database(s) a company uses:
