Review Comment:
   > - In `datafusion::physical_plan::planner::tests::errors()`, tests for 
`like/ilike/not like/not ilike` are removed, as for `Expr::Like` and 
`Expr::ILike`, `coerce_types` are not performed in `Expr::get_type`

   However, these kind of errors will be checked in `TypeCoercionRewriter`
