Marek Vavruša	e936c4d066	AggregateFunctionSum: implemented sumWithOverflow(x) ... By default sum(x) promotes the result type to largest possible integral type to avoid arithmetic overflow when summing values from smaller data types. This is generally desirable behaviour, but it doesn’t work with summing merge tree, as the result is expected to be of same type as the input.	2017-10-25 22:21:59 +03:00
