 # Numeric aggregators on STRING columns and string literals.
 # A STRING column is implicitly cast to a number for SUM, AVG and COUNT; MIN 
and MAX reject it.
+# A string literal that cannot be parsed as a number is rejected by SUM and 
AVG.

Review Comment:
   Nit: this check isn't limited to SUM and AVG. `BIT_AND`/`BIT_OR`/`BIT_XOR` 
(cases 36-38 below) and the variance functions (`VarianceSqlAggregatorTest`) 
are rejected as well. Maybe something like "...is rejected by numeric 
aggregators such as SUM, AVG and BIT_AND"?
