When loading pages in my Django + Postgresql setup I occasionally get this error but not all the time:
psycopg2 in connect
InterfaceError: only protocol 3 supported
psycopg2/__init__.py ? in connect raise TypeError('missing dsn and no parameters') else: dsn = " ".join(["%s=%s" % (k, _param_escape(str(v))) for (k, v) in items]) conn = _connect(dsn, connection_factory=connection_factory, async=async) if cursor_factory is not None: conn.cursor_factory = cursor_factory return conn I have absolutely no idea what could be causing this.
My production.py settings file:
DATABASES = { 'default': { 'ENGINE': 'django.db.backends.postgresql_psycopg2', # Add 'postgresql_psycopg2', 'mysql', 'sqlite3' or 'oracle'. 'NAME': 'mydbname', # Or path to database file if using sqlite3. # The following settings are not used with sqlite3: 'USER': 'myuser', 'PASSWORD': 'mypassword', 'HOST': 'localhost', # Empty for localhost through domain sockets or '127.0.0.1' for localhost through TCP. 'PORT': '', # Set to empty string for default. } }
