Replication or not, why are you running pgbench on a production server?

And by "shoot myself in the foot", are you asking whether it would overwhelm some system or another, thereby breaking replication?  If so, we can't answer that, since we don't know the hardware specifications, your current workload, and whether or not you're doing synchronous or asynchronous replication.
