X-Git-Tag: REL9_5_5~55 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=b93d37474fdf31d2cd71c13f014b481863abb7c2;p=thirdparty%2Fpostgresql.git Fix pgbench's calculation of average latency, when -T is not used. If the test duration was given in # of transactions (-t or no option), rather as a duration (-T), the latency average was always printed as 0. It has been broken ever since the display of latency average was added, in 9.4.
