Set partitioned_rels appropriately when UNION ALL is used.
In most cases, this omission won't matter, because the appropriate locks will have been acquired during parse/plan or by AcquireExecutorLocks. But it's a bug all the same. Report by Ashutosh Bapat. Patch by me, reviewed by Amit Langote. Discussion: http://postgr.es/m/CAFjFpRdHb_ZnoDTuBXqrudWXh3H1ibLkr6nHsCFT96fSK4DXtA@mail.gmail.com
