I'd thought about hacking this capability into pgbench-tools, so that there was a new outer-most loop that iterates through different postgresql.conf files. Come to think of it, the need to vary settings per test set (that is, per series of benchmarks, each of which is plotted as a different color) generally only exists for one or two settings, so it is probably better to pursue the approach that you propose here. I guess what I've outlined could still be useful for PGC_POSTMASTER gucs, like shared_buffers. -- Regards, Peter Geoghegan -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
