As far as I understdood Robert's criticism it was more about the internals, than about the userland representation. To me it's absolutely clear that 'real partitioning' userland shouldn't be based on the current hacks to allow it. But I do think that a first step very well might reuse the planner/executor smarts about it. Even a good chunk of the tablecmd.c logic might be reusable for individual partitions without much change.
