Right, I think this is left over from initial version where parallel seq scan
was supported just for single table scan. It should probably do similar to
create_seqscan_path() and then pass the same down to
create_partialseqscan_path() and get_baserel_parampathinfo().
Thanks, I will fix this in next version of patch.
