One supposes horrifically slow might be a bit subjective. I notice in a VM on my laptop establishing the initial connection to postgres seems to take 2-3ms, and running a trivial query takes 300-1000us. I routinely involve the database in unit tests, it is certainly slower but my primary concern is the correct behavior of production code which uses real databases.
