rebuild_rel() does the rebuilding steps. Truncate uses this skipping
the datacopy stage by calling with dataCopy = false.

If wanted (separate patch), the below could (should?) probably move to
heap.c:
rebuild_rel
make_new_heap
copy_heap_data
swap_relfilenodes

The below could (should?) move to index.c:
get_indexattr_list
recreate_indexattr

That leaves the below in cluster.c:
cluster_rel
cluster
check_cluster_ownership
get_table_to_cluster
