Once you've opened a connection, you can toggle the printing of the
exact query sent to the database as follows:

|>> from pyPgSQL import PgSQL
|>> cx = PgSQL.connect()
|>> cx.conn.toggleShowQuery	<-- this toggles printing the query on
'on'
|>> cu = cx.cursor()
QUERY: BEGIN WORK
|>> cu.execute('select * from test where b = %s', 'bga')
QUERY: DECLARE "PgSQL_-40B25954" CURSOR FOR select * from test where b =
'bga'
QUERY: FETCH 1 FROM "PgSQL_-40B25954"
QUERY: SELECT typname, -1 , typelem FROM pg_type WHERE oid = 23
QUERY: SELECT typname, -1 , typelem FROM pg_type WHERE oid = 1043

Accessing cx.conn.toggleShowQuery again will turn off the printing of
the queries.
