Uh, why fallback_application_name? Isn't this the *exact* usecase
where "application_name" should be used? At least for the two apps -
fallback_app_name might be correct for dblink.
And yes, I think it's a good idea to set it for at least pgbench and oid2name.

I think that's a pretty bad idea in general. But if we do, then it
should at least never override something that's specified - we need to
keep the ability for tools like psql and pgadmin to set it, regardless
of what they happen to have as argv[0].
