+  # Binary operators tokens
 
 Review comment:
   This is extended from the core parser which is used for customizing the binary operator tokens, for example, in PostgreSQL, we can have a `::` token to implies `CAST` operator: `a :: INT` is equals to `CAST(a as INT)`.
   
   For Flink, we does not need this now, the parser just complains if we does not have such section.
