Description
On a raw query like below, causes the dapper doesn`t never return or "error unknown 0 code"
- sum(n_numeric_field * (n_other_numer_field/1000) * (n_other_numer_field/1000))
After some hours I discovered it is caused because this formula results a number with a lot of decimals that do not fit on decimal on c# .net core. To solve this I needed to force round on query.
Dapper needs to improve handle this kind of error and show better messages

No source file, test, or entry point is identified. Reproduce the raw PostgreSQL query using the shown decimal expression, then trace how Dapper surfaces the conversion failure; done means the query reports a useful error instead of hanging or returning an unknown error code.
