Does anyone have suggestions for a utility that would easily let us mirror all queries to a "shadow" PG cluster, so that we can compare performance of our current production config against a new proposed config with our actual production traffic?
(We could live with the new one falling behind as long as queries were queued not lost--in fact we know this will happen.)
PgShark might work for this
