 The aggregate expression functions AVG, MEDIAN, STDDEV and SUM do not
 support byte values as an input data type although this is a valid input
 data type. Therefore, the following signature needs to be added to the
 signature list for each of the mentioned functions:

 AVG:    FdoDataType_Double AVG    ([{ALL | DISTINCT}, ] byte_value)
 MEDIAN: FdoDataType_Double MEDIAN (byte_value)
 STDDEV: FdoDataType_Double STDDEV ([{ALL | DISTINCT}, ] byte_value)
 SUM:    FdoDataType_Double SUM    ([{ALL | DISTINCT}, ] byte_value)
