Patch applies with "patch", but not with "git apply", probably because it is in CR-NL eol format. No big deal.
Documentation has been switched from SGML to XML, so now tags must be explicitely closed, i.e. use <foo>x</foo> instead of <foo>x</>.
Patch compiles with a warning:
pgbench.c: In function ‘getZipfianRand’: pgbench.c:905:2: warning: ISO C90 forbids mixed declarations and code [-Wdeclaration-after-statement]
Declaration must move before assertion.
The random_zipfian(1,100,2) call result is not tested.
"1 times" -> "once".
"array overflow on \random_zipfian" remove spurious "\".
