> This is a cursed idea to begin with, so I can't fully blame PostgreSQL.

After going through the list, I was left with the impression that the "cursed" list doesn't really refers to gotchas per se but to lessons learned by the developers who committed them. Clearly a couple of lessons are incomplete or still in progress, though. This doesn't take away from their value of significance, but it helps frame the "curses" as persona observations in an engineering log instead of statements of fact.
