Oh, never mind; now I realize that the point is that you didn't ever
iterate over those leaf indexes.
However, consider a thought experiment: assume for whatever reason that
all the actual index builds happen first, then all the cases where you
succeed in attaching a sub-partitioned index happen at the end of the
command. In that case, the percentage-done indicator would go from
some-number to 100% more or less instantly.
What if we simply do nothing at sub-partitioned indexes? Or if that's
slightly too radical, just increase the PARTITIONS_DONE counter by 1?
That would look indistinguishable from the case where all the attaches
happen at the end.
