Subject: pgsql: Set random seed for pgbench.
Date: Mon, 26 Mar 2018 15:26:47 +0000
Message-ID: <E1f0U1H-00005J-98@gemulon.postgresql.org> (raw)
Set random seed for pgbench.
Setting random could increase reproducibility of test in some cases. Patch
suggests three providers for seed: time (default), strong random
generator (if available) and unsigned constant. Seed could be set from
command line or enviroment variable.
