(emphasis mine) This has a "from [A] to [B] and [C]" structure, but the 'to' in the sentence isn't part of that structure; instead it's part of "allowing merge joins *to* use incremental sorts" (we had merge joins and incremental sorts before, they just didn't work together yet). This caused a double-take on my end. I think it would be easier to read if it was instead written as "from [A] to [B]" as follows: [...], *from* improving the overall performance of hash joins *to* allowing merge joins to use incremental sorts. ... optionally with one more such feature added to allow the use of "and" in this too. > ### Upgrading I'd rename this section to "Upgrade performance", "Upgrade experience", or "Upgrade workflow". Reason: Most new release posts which have a section "Upgrading" which contains details on how to upgrade, while this section is about improvements in the upgrade workflow of PostgreSQL. This difference also initially caused me to skip the section when doing an initial pass for fact checks. Hope these aren't too nitpick-y. Kind regards, Matthias van de Meent Neon (https://neon.tech)
