flink filterpushdown can not take effect in blink planner

When i use the filterpushdown , i found the FilterPushDown only take effects in orc/parquet/testFilter  when using flink planner.

Because the call  applyPredicate(List<Expression> predicates) predicates 

1) PlannerExpressin flink planner the PushFilterIntoTableSourceScanRule  RexProgramExtractor.visitCall return PlannerExpression

2) CallExpression  blink planner , can not match current And Or EqualTo and so on, which it PlannerExpresion  the PushFilterIntoTableSourceScanRule  RexNodeExtractor.visitCall return ResolvedExpression
