1) restore child and parent index (order doesn't matter);
2) attach child index;
3) set cluster on child and parent index (order doesn't matter);

..since it needs to be restored after any child indexes are restored *and

1) restore child and parent index (order doesn't matter);
2) attach child index;
3) set cluster on child and parent index (order doesn't matter);

1) restore child and parent index (order doesn't matter);
2) attach child index;
3) set cluster on child and parent index (order doesn't matter);

1) restore child and parent index (order doesn't matter);
2) attach child index;
3) set cluster on child and parent index (order doesn't matter);

1) restore child and parent index (order doesn't matter);
2) attach child index;
3) set cluster on child and parent index (order doesn't matter);

..since it needs to be restored after any child indexes are restored *and

1) restore child and parent index (order doesn't matter);
2) attach child index;
3) set cluster on child and parent index (order doesn't matter);

..since it needs to be restored after any child indexes are restored *and

2) attach child index;
3) set cluster on child and parent index (order doesn't matter);

In the mood of removing long because it may be 4 bytes or 8 bytes
depending on the environment, I'd suggest to change it to either int64
or uint64. Not that it matters much for this specific case, but that
makes the code more portable.

Then you're going to need a not-so-portable conversion spec in the
snprintf call. Not sure it's any improvement.
