How do I use Psycopg2's LoggingConnection?

Question

I\'d like to log the queries that psycopg2 is making, but the psycopg2 documentation doesn\'t really specify how LoggingConnection should be used.

import log

Seems like setting the connection_factory=LoggingConnection works

import logging
import psycopg2
from psycopg2.extras import LoggingConnection

logging.basicConfig(level=logging.DEBUG)
logger = logging.getLogger(__name__)

db_settings = {
    "user": "abcd",
    "password": "efgh",
    "host": "postgres.db",
    "database": "dev",
}

conn = psycopg2.connect(connection_factory=LoggingConnection, **db_settings)
conn.initialize(logger)

cur = conn.cursor()
cur.execute("SELECT * FROM table LIMIT 5")
