PostgreSQL has been around for almost 27 years (and even longer, if you include the Ingress and Post-Ingress eras). And things, well things, they tend to accumulate, to quote Trent Reznor, heh. On a related note, one could say that the C++ Core Guidelines[1] at least partially represent such a list. 55 matches for “don't use” and 247 for “avoid”, although not all of them are about language features, obviously.
