I have to wonder if there really *is* a use case for CLUSTER in the
first place on regular tables, let alone on partitioned tables, which
are likely to be large and thus take a lot of time. What justifies
spending so much time on this implementation? My impression is that
CLUSTER is pretty much a fringe command nowadays, because of the access
exclusive lock required.
Does anybody actually use it?
