> In EXPLAIN_LEVEL 2, "parquet predicate statistics" combine conjuncts from 
> multiple tuple descriptors into one line:
>     parquet statistics predicates: c_custkey > 0, o.o_orderkey > 0, 
> l.l_partkey > 0
> However, "predicates" separate the conjuncts into a line per tuple descriptor:
>     predicates: c_custkey > 0, !empty(c.c_orders)
>     predicates on o: !empty(o.o_lineitems), o.o_orderkey > 0
>     predicates on l: l.l_partkey > 0
> These two cases should be consistent. Prefer the line per tuple descriptor 
> style.
