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 type I/O overhead. Not a huge performance win for common cases, but if someone were passing larger arrays around, it could be quite beneficial. -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
