PyAgg Helper Function
CDB_pyAgg (columns Numeric[])
Currently it's not possible to pass a multidiemensional array between plpsql and plpythonu. This function aims to help fix that by aggergating the columns provided in the argument across rows in to a rows * columns + 1 length 1D array. The first element of the array is the array_length of the columns argument so that python can reconstruct the 2D array.

A table with the following columns.
| Column Name | Type | Description |
|---|---|---|
| result | NUMERIC[] | An columns * rows + 1 array where the first entry is the no of columns |
