The following bug has been logged on the website:
Bug reference: 15819
Logged by: KOIZUMI Satoru
Email address: koizumistr(at)minos(dot)ocn(dot)ne(dot)jp
PostgreSQL version: 11.3
Operating system: (Any)
Description:
In example of random_zipfian, the explanation is "which itself(2) is
produced (3/2)*2.5 = 2.76 times more frequently than 3".
"(3/2)*2.5 = 2.76" is wrong. The correct expression is "(3/2)**2.5 = 2.76".
