PostgreSQL provides a facility to define columns as an array with any valid data type, array should be. We can now easily document the array_length behavior of returning null. instead of zero for an empty array/dimension. I added an example to the json_array_length function to demonstrate that it. does return 0 as one would expect, but contrary to the SQL array behavior. I did not bother to add examples to the other half dozen or so "_length". Array is used collect one column of query result data.
