> Currently user-defined aggregate functions must have one parameter.
> SqlAggFunction need new constructor to set paramTypes to allow user-defined
> aggregate function to have more than one parameter.
> If a class(A) implement interface of AggregateFunction,that instance of class
> will be transformed to instance of SqlUserDefinedAggFunction by call toOp
> method in CalciteCatalogReader.
> when construct the SqlUserDefinedAggFunction instance will set paramTypes to
> null for super class sqlFunction indirectly.
> The problem is:
> we will get SqlUserDefinedAggFunction paramTypes to sql validatefilte,but it
> will be filter nothing
