pgsql: Doc: improve documentation about random().

2022-07-23 Thread Tom Lane
Doc: improve documentation about random(). We didn't explicitly say that random() uses a randomly-chosen seed if you haven't called setseed(). Do so. Also, remove ref/set.sgml's no-longer-accurate (and never very relevant) statement that the seed value is multiplied by 2^31-1. Back-patch to v12
