Description

The types `TINYINT` and `DOUBLE` do not exist in Postgres, so attempting to cast to them throws a runtime exception, e.g.

 

// query
select CAST("store_id" as TINYINT) from "foodmart"."expense_fact"

// exception
java.lang.RuntimeException: exception while executing [select CAST("store_id" as TINYINT) from "foodmart"."expense_fact"]
