      Description

      Currently, the RexNodeToExpressionConverter in both planners are not fully support. There're many RexNodes can not be converted to Expressions.

      1) RexFieldAccess -> GET call
      2) Literals in interval types and complex types and TimeUnitRange
      3) TRIM(BOTH/LEADING/HEADING, ..)
      ...

      We should have a comprehensive tests to cover all cases. A good idea is to verify with ExpressionConverter together.
