I think there's nothing that fails to suck about a hardwired "+ 10".
We should either remove that and use effective_io_concurrency as-is,
or decide that it's worth having a separate GUC for bulk operations.
At this stage of the cycle I'd incline to the former, but if somebody
is excited enough to prepare a patch for a new GUC, I wouldn't push
back on that solution.
