1. DELETE/UPDATE more than one row in partitioned foreign table (1/2)

   There is known bug in delete and update rows in partitioned foreign
   tables via FDW [1]
   Current copyTuple and copySlot machinery supposes that
   source and destination slots and tuples always match. This patch modifies
   copy internals to consider more complex case and copy only actual attributes,
   and if destination slot/tuple has more they are set to null. This is a proof
   of concept patch which shows such mechanics does not break anything and
   allows to use it in cases when we have to pass or receive not matching number
   of attributes.
   Core patch - introduction of remote table OID returned from remote
   query and passing it through planner and executor to use in foreign
   queries
