If the python library sends the query+parameters you can't because it is
the backend that will build the final query. Currently psycopg does all
argument escaping and quoting on the client so we have the final query
ready for inspection.

Anyway, if the client library sends query+parameters to the backend it
is possible to build a "fake" query for logging/debugging purpuse. For
example, we plan to move psycopg .executemany() to prepared queries and
even in that case .mogrify() will return the full query, but in that
case it will be not the one we sent to the db.

 There's no greys, only white that's got grubby. I'm surprised you
  don't know that. And sin, young man, is when you treat people as
  things. Including yourself.                       -- Granny Weatherwax
