Hi.
I attempted to make the following measurements using PostgreSQL 9.6.0
pgbench on CentOS 7.
$ pgbench -P 5 -R 400 -C -S -r -c 4 -T 30 bench -U postgres
However, this benchmark did not work properly.
* I refer to pg_stat_activity, but no connection from pgbench to PostgreSQL.
* pgbench does not stop even after the time specified by the -T option
elapses.
It operates normally when only the -C option or only the -R option is
specified.
In the PostgreSQL document, It is not described that "these two options can
not be specified at the same time ".
Is this a problem of pgbench?
