Convert is not a good word choice. The Datum of the parameter is stored inside a new Python object(that only holds a
Datum).So more like "copied into Python memory", and associated with its respective type. Wrapped in a Python object?
One cool thing about doing it this way, is that if you just pass parameters forward to a prepared statement, there's no
typeI/O overhead. Not a huge performance win for common cases, but if someone were passing larger arrays around, it
couldbe quite beneficial.
