There is no mogrify, no, because queries are not composed by the
client anymore, but they are sent to the server separately from the
arguments. Mogrify would be misleading because the same query might
behave differently if parameters are merged by the server or by the
client.
The logging cursor, I don't think should exist as an option: the
logging system itself has the option of being enabled or disabled. So,
if any, I think psycopg should log every query, let's say at info
level, which would normally be discarded, unless the user enables it
with a getLogger("psycopg").setLevel(logging.INFO). However that's not
in, because I have a fear (but not a measure) that it would add some
overhead. Which is totally premature optimisation, I am aware.
Maybe someone would like to help and get some measurement of how much
overhead does logging add? Comparing no logging/disabled
logging/enabled logging?
