>Postgres 17.0 has been out for a bit and it’s awesome, but here’s the reality: most Postgres users won’t upgrade right away. Most probably aren’t even on 16.4 or 16.anything —they’re probably still using Postgres 15 or an even older version.
So, by "ancient", this author means possibly not even two years old, as Postgres 15 is barely that old (https://www.postgresql.org/about/news/postgresql-15-released...).
Meanwhile, I've had to make posts this year to tell people no, seriously, stop using Python 2.7.
And meanwhile in my package repo:
$ apt show postgresql
Package: postgresql
Version: 14+238
Priority: optional
Section: database
Source: postgresql-common (238)
Origin: Ubuntu
Maintainer: Ubuntu Developers <ubuntu-devel-discuss@lists.ubuntu.com>
The author's expectations are incredibly unrealistic.
