描述
It appears that (at least in Postgresql), summing a list of ints gives back a numeric. So when you call sum_ from esqueleto on an Int column and use the result as an Int you get a persist marshal error. IMO this should probably be solved on esqueleto's end, by either inserting an explicit cast or by restricting the return type of sum_ to ones which will not raise a marshal error.
