How to import the "connection" class from psycopg2?

I want to import specifically the connection class from psycopg2 because I want to specify that the argument to one of my functions is indeed a valid psycopg2 connection.

But I am having trouble locating exactly where it is stored. The doc page is here but I can't seem to find any reference to where it is defined, and poking around in the source code has left me more confused.

So far I have tried:

from psycopg2 import connection
from psycopg2.extensions import connection
from psycopg2.extras import connection
from psycopg2.sql import connection

But none of them are valid references

You can find it here:

from psycopg2._psycopg import connection

But this is an internal object, so you shouldn't do that. It is meant that connection objects are created via psycopg2.connect() factory method.
