I'm looking at function scope, and wonder what's the best approach and
perhaps some description what each scope means.
Min/Max is marked as Point_aggregate scope, which I thought it's
holistic_aggregate.
There isn't any comments on these, and only point_aggregates is used,
I wonder what does each other one mean?
SIMPLE,
POINT_AGGREGATE,
DECIMAL_AGGREGATE,
HOLISTIC_AGGREGATE,
RANGE_AGGREGATE,
And should I care about the others here?
DECIMAL_MAX_SCALE,
DECIMAL_SUM_SCALE,
DECIMAL_CAST,
DECIMAL_DIV_SCALE,
DECIMAL_SET_SCALE,
DECIMAL_ZERO_SCALE;
