Depends on your shop.

As someone with a heavy QA/Dev Opps background I don't think we have enough details.

Is it only ARM64 ? How many ARM64 PG DBs are running 96 cores?

However...

This is the most popular database in the world. Odds are this will effect a bunch of other lesser known applications.

Thank you for sharing.

So it looks like an edge case, as usually you need huge pages at scale ??
