> In some cases we may need to have a hook that activates before a query
> compilation and after its execution. For instance, dynamically generate a UDF
> specifically for the running query and clean up the resource after the query
> is done. The current hooks only covers pre & post semantic analysis, pre &
> post query execution, which doesn't fit the requirement.
