In principle, the client knows the database name. In practice, if it's
coming from PGDATABASE or via a service configuration, one may be confused
about the database; having the error message be explicit will avoid many
problems. I can easily imagine that "unable to connect to database" would
be mystifying, whereas "unable to connect to database foo" would elicit the
response, "wait, I'm trying to connect to what now?" leading much more
quickly to a resolution.
