Review Comment:
   Remove this test because now parameters will be cast to the target type. 
   This is also the behavior of PostgreSQL.
   ```sh
   psql=> prepare p(int) as select 100+$1;
   PREPARE
   
   psql=> execute p('100');
    ?column?
   ----------
         200
   (1 row)
   
   psql=> execute p(20.12);
    ?column?
   ----------
         120
   (1 row)
   ```
