Description

Currently in AbstractStructVector#getPrimitiveVectors, only struct type child vectors will recursively get primitive vectors, other complex type like ListVector, UnionVector was treated as primitive type and return directly.

For example, Struct(List(Int), Struct(Int, Varchar)) getPrimitiveVectors should return [IntVector, IntVector, VarCharVector] instead of [ListVector, IntVector, VarCharVector]
