Explain format for parquet predicate statistics should be consistent with predicates

    Details

    • Epic Color:
      ghx-label-6

      Description

      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.
