yes, this is correct, an error of mine. Thanks!

The datatype.format method takes a datasource as a second argument so 
it can check if the datasource provides any format function for that 
specific datatype.

There's a default format() function for any kind of SQL literal (for 
most Python's str() function does the trick) but if some backend 
needs a special format, it can provide an appropriate format 
function.
