My kneejerk reaction to the headline is ‘why would it?’.

It’s unsurprising to me that an AI company appears to have chosen exactly the wrong tool for the job.

Because documentation doesn’t warn about this well-loved feature effectively ruins the ability to perform parallel writes, and because everything else in Postgres scales well.

I think it’s a reasonable assumption. Based on the second half of your comment, you clearly don’t think highly of “AI companies,” but I think that’s a separate issue.
