Makes partition descriptor acquisition faster during the transient period in which a partition is in the process of being detached. This also adds the restriction that only one partition can be in pending-detach state for a partitioned table. While at it, return find_inheritance_children() API to what it was before71f4c8c6f7, and create a separate find_inheritance_children_extended() that returns detailed info about detached partitions. (This incidentally fixes a bug in8aba932251whereby a memory context holding a transient partdesc is reparented to a NULL PortalContext, leading to permanent leak of that memory. The fix is to no longer rely on reparenting contexts to PortalContext. Reported by Amit Langote.)
